Experience with Mapping

Posted by Amisha Singla on 23 August 2016 in English (English)

I decided to spend some time mapping on OpenStreetMap after starting at Mapbox to help build better mapping tools later. After having show and tells with Mapbox buddies, I started off with mapping my hometown. Though I had not very perfect memory of the places in my hometown as I am away from it from many years, but there were few places which I was sure about. As it is advised to add data with 100% accuracy only, therefore I tagged only the sure places in OSM. When I downloaded the data for my city Gandhidham in JOSM, to my surprise, the city was well traced by a remote mapper. Therefore I worked on adding known POIs. It was fun to look for my home from the satellite imagery and tag its address.

Next I traced roads in city called Raipur. It was like taking part in an enjoyable drawing task while keeping a few rules in mind. Adding intersections, junctions, classification of roads has a huge impact on the routing. So I did that quite carefully.

Later I moved on to tracing buildings in Baga Beach, Goa. While working on this task I found many buildings that were quite interesting. Also, there were many row houses present in that area. Therefore to do it efficiently, I tried exploring the shortcuts of JOSM i.e. Making a big building and splitting it into pieces.

The most fun and interesting part of mapping was Field Mapping. To execute this we went in a group and split into sub-groups for covering a bigger region to map. I teamed up with Srividya. We planned to collect details like building addresses, levels, amenities , trees, streetlights in the neighborhood area of Mapbox office.We used OSM Tracker, mobile application for field mapping. For mapping all the buildings and amenities, we assigned each building a text note with all its details and took few photographs of the same which later helped us to upload the information in JOSM. For mapping trees and streetlamps , the presets came in handy, as you just have to tap on the mobile screen, whenever you encounter any tree or streetlamp. But the problem being we could not find any preset for tree and streetlamp. Therefore Srividya and me found out this trick to encode things up. We used 'Shelter' preset for tree and 'Surveillance' preset for streetlamp. Field mapping helped to explore and understand the neighborhood better.

Overall, mapping the places was a wonderful experience. Looking forward to keep making more edits in OSM.

Learning Mapping

Posted by Amisha Singla on 23 August 2016 in English (English)

What is Mapping?

It is an operation which associates elements of one set with the one/more elements of another set. When we talk about mapping in OpenStreetMap, the similar concept is followed. In that, we associate the real life objects (Home, Parks, Schools, Roads, Water bodies) to 2D elements like node, ways and polygons. This means that we can traverse any place virtually by looking at the map and can a get a sense of directions, locality, etc.

What are the objects which can be mapped?

It can be mapping different amenities, POIs, roads, buildings, water bodies, turn restrictions, different transport networks, Trees, Street lamps, so on. This list is never ending as each of them has a special purpose of being added in the map. The more detailed it is, the more it helps in understanding the place geographically. Details

How do we Map?

Basically there are two steps involved to map a place:

  • Tracing - With the help of satellite imagery and tools like In-browser editor/JOSM, one is able to trace various buildings, roads, water bodies remotely. For learning JOSM, one can follow this blog. Tracing

  • Tagging - Once we are done with tracing, we can start adding particular details like name, type, etc depending what kind of entity ( node / way / polygon) it is. If one is well familiar with the details of the place, then it can be done remotely. The best example for it will be mapping your hometown. For the mapping the unfamiliar places, Field mapping comes in picture. It is a technique in which a person goes to the actual area and maps it. There are mobile applications like OSMTracker, Vespucci which are helpful for field Mapping. One can also use the field papers. To learn more about field mapping, one can follow this blog. Labelling

Progress of Navigation Mapping in Canada!

Posted by poornibadrinath on 23 August 2016 in English (English)

With an aim of making OpenStreetMap more navigable and accurate in routing, we started mapping turn restrictions and exit-destinations in Canada in its five important cities: Toronto, Ottawa, Montreal, Vancouver and Calgary. The tasks which spread over a month have been completed; we have finished adding and validating both turn restrictions and exit-destinations in the selected cities of Canada with the support from the OpenStreetMap community.

Summary of improvements

Mapping turn restrictions was flagged off on 21 of July with data team and the community working on adding missing turn restrictions and validating the ones that are present.

As the mapping progressed, workflow was getting updated every time the team had some doubts regarding how best to map a particularly different turn restriction that was detected. The questions we had were posted on the mapping ticket we used and the community got back to us almost immediately with clarifications to our questions. We completed both adding and validating turn restrictions in 14 days.

Exit-destination mapping started on August 11. For exit and destinations, a slightly different approach was followed, unlike how we mapped previously using only checkautopista2. Each highway was considered a separate task, which was integrated into tasking manager, with a specific link to checkautopista2 that loaded that particular highway that was selected using tasking manager.

Below is the full breakdown of how many turn restrictions and exit-destinations were mapped:

Status of existing data and Mapillary coverage

We could map extensively in Toronto because of great Mapillary coverage. Ottawa had us verifying the existing exit-destination tags rather than adding new ones because most of them were already mapped. 🎉 The community raced us in adding exit-destination tags in Vancouver! 🚀 Due to less Mapillary coverage, we couldn't map much in Montréal and Calgary. We wrapped up adding and validating exit-destinations in 9 days :)

Community support

Both the projects were met with an amazing response from the community. It was great to have you all working alongside us, helping us in adding missing data, calling out and correcting our errors, keep tabs on our edits, and clarifying doubts and questions, letting us make edits to previously added data. We thank everyone, especially Andrewpmk, Rps333, James2432, Bootprint, Puec, Fmarier, Scruss, for your support and guidance and hope the collaboration and involvement continues in all our future projects. We will continue navigation mapping in Canada, specifically in Montreal and Calgary once there is enough Mapillary or OpenStreetView coverage for us to add data and verify them.

Until then,

Cheers!

Mapbox Data Team :)

Spotting Cemeteries in Texas

Posted by mvexel on 23 August 2016 in English (English)

I am collaborating with agencies in Texas to update both OSM and Texas data. The pilot project deals with cemeteries. I received a file with almost 7000 cemetery locations. (Even if the idea that there are more people living today than have died thus far in human history turns out to be a myth, I think that is quite a lot!).

The first phase of this collaboration is to see which cemeteries in the Texas data actually exist. We will use MapRoulette for that. Simply go to the Cemetery challenge at maproulette.org and start looking at tasks.

If you see a cemetery in the aerial image, click 'skip' to go to the next one. If you don't see a cemetery, click 'False Positive'. If you are in doubt, click 'skip'.

How can you tell if there is a cemetery? Sometimes it is hard. Look for fine patterns defining the plots, and usually there will be a service road connecting the cemetery to the road network. Sometimes, in larger cemeteries, you may also see paths inside the cemetery. Finally, the marker may not be right on the cemetery, so look around a bit as well. Below are some examples of cemeteries and non-cemeteries.

Once we complete stage 1, we will turn to mapping all the cemeteries that are not yet in OSM yet!

Status der OpenTopoMap

Posted by derstefan on 22 August 2016 in German (Deutsch)

Die OpenTopoMap feiert am 03.09. seinen fünften Geburtstag! Als Versuch gegründet von zwei Studenten unterschiedlicher Fakultäten entwickelte sich die OTM zu einem Kartenprojekt, das mittlerweile nicht nur innerhalb der OSM-Community ein Begriff ist. Das heutige Kartenbild hat sich im Vergleich zum allerersten Testbild glücklicherweise weiterentwickelt: OTM 2012 Zum Vergleich: OpenTopoMap heute

Auch die Besucherzahlen und damit die Anforderungen an die Hardware stiegen kontinuierlich. Derzeit rufen gut 30.000 Besucher mehr als 90 Mio. Kacheln pro Monat ab. Die Garmin-Downloads, die glücklicherweise auf einem anderen Server liegen, kommen auf 17 TB/Monat. Besucher Zugriffe

Möglich ist der Betrieb überhaupt nur durch die Unterstützung der Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) und dem Regionalen Rechenzentrum Erlangen (RRZE). 2012 finanzierte die Universität dem Projekt einen Server, der dankenswerterweise am RRZE untergebracht und versorgt wird. 2015 finanzierte das Department Geographie eine SSD mit 1,1 TB, die über PCIe angebunden ist. Und erst vor Kurzem wurden von der Universität dankenswerterweise Mittel für weitere HDDs im RAID mit 3,6 TB nutzbarem Speicherplatz bewilligt, um auch die größeren Zoomstufen vorhalten zu können.

Seit Anfang 2016 konnte dank der 1,1TB-SSD der Versuch gewagt werden, den gesamten Planeten abzudecken. Selbst die minütlichen Updates brachten den Server bezogen auf die Rechenzeit nicht mal ansatzweise an seine Grenzen. Die OSM-Datenbank (osm2pgsql ohne HSTORE) wuchs allerdings so stark, dass der automatische Import vor wenigen Wochen gestoppt werden musste. Neben den OSM-Daten (495 GB) liegen nämlich auch 505 GB an Höhenlinien als Datenbank auf der SSD.

Die Konsequenz ist klar: Die Höhenlinien-Datenbank muss um mindestens 100 GB reduziert werden, um der OSM-Datenbank Platz für die nächsten Monate und Jahre zu verschaffen. Auch kartographisch wäre dies sinnvoll: Der weltweite Höhenlinienabstand von 10 Metern ist spätestens in Hochgebirgen alles andere als übersichtlich (Beispiel). Man kann also getrost auf so manche Höhenlinie verzichten. Das Problem ist nur, einen Algorithmus und dessen Parameter zu finden, mit dem automatisiert alle Höhenlinien weltweit ausgedünnt werden können. Übrigens enden Höhenlinien auf professionellen Karten durchaus auch mal im Nichts, wenn zwischen Detailgraden gewechselt wird. Vermutlich muss man nach (evtl. zusammenhängenden) Gebieten suchen, in denen Höhenlinien gelöscht werden.

Derzeit bin ich der einzige technische Entwickler der OpenTopoMap. Glücklicherweise habe ich neben der OTM noch andere schöne Hobbys, wodurch die Entwicklungszyklen allerdings extrem lang werden. Gerne würden wir weitere Entwickler aufnehmen und nach der Höhenlinienproblematik auch weitere Ideen ausprobieren. Sehr willkommen (und sich in einer E-Mail-Flut äußernd) sind natürlich weiterhin Anregungen und Verbesserungsvorschläge. Ohne ein Entwicklerteam, das größer als eine Person ist, stehen die Chancen auf eine schnelle Umsetzung allerdings schlecht.

Lange Rede, kurzer Sinn: Wir suchen nach Entwicklern! Wer sich berufen fühlt, möge sich gerne bei mir per PM oder Mail (stefan@opentopomap.org) melden.

Die Autoren des Projektes möchten nochmals ganz herzlich der FAU und dem RRZE für die Finanzierung und Unterstützung der OpenTopoMap danken.

Speed limits split ways

More speed limit changes in town centres. They need to be captured but I don't like breaking up the roads into little pieces. Subsequent searches just return a little bit of the original road.

# Wrapping up Google Summer of Code

Posted by kepta on 22 August 2016 in English (English)

3 months have passed and GSoC is about to an end. This small diary post showcases my contributions uptill now and it also lays down my next actions.

Major Contributions

Lane editor

The lane editor is my primary objective of the GSoC for this summer. These diary posts (1, 2) can be referred to get updated with the work.

Currently, most of the functional code is ready with 81 test cases testing most if not all edge cases possible. This code parses the osm data and gives a nice JSON output, which should then be supplied to the rendering.

Making iD modular

The iD contributors felt the need to start using the new ES6 module system back in April. I helped in the phase 1 and phase 2 of this process.

OSM hackday

I was a part of organizing team of this small hackday at Mapbox Bengaluru. More info

Next Steps

Well GSoC 2016 is approaching an end, but not my contributions. There are lot of things pending in my bucket list. The first thing I would like to finish in the coming months would be the lane editor's UI and deploy it for the use of OSM community.

I am really proud to be one of the core contributors of iD and would really like to thank the community, my mentor Bryan Housel and Google for the awesome GSoC program.

Columbus V990 Cover : Handmade for fun

Posted by parambyte on 22 August 2016 in English (English)

I love the Columbus V990 as a tool for data gathering, not only for its long battery life (about 12-16 hours) and extreme ease of use, but also for its precision and price. Everything works. But what doesn't is its cover. I took the dimensions of the V990, and had a sleeve handcrafted. Its available for sale at Flipkart.com just look for StudioLove (one word).

I am hoping to create a small fund out of sale proceeds to help the community.

OSM in Disaster Risk Management

Posted by Manjurul Islam on 21 August 2016 in English (English)

OSM data is very helpful for disaster risk management. This data is helpful for identification of vulnerable places ,way of passing, important key indicator etc. As the proper authority get the information they will take necessary steps to reduce the destruction of disaster.in this map we get the data about building condition, material, structure by research this information govt. /relevant authority will identify the vulnerable places and take necessary steps to reduce the vulnerability ,to reduce the damage of any kind of disaster . By using this data Bangladesh Red Crescent society or like this type of voluntary organization or Government organization like fire service , civil defense will plan their search & rescue operation. It will helpful for VCA(Vulnerable Capacity Assessment).

A Suggestion to Fix Poor LSN in the UK

Posted by alexkemp on 20 August 2016 in English (English)

This is a research document; it is going to attempt to explain:—

  1. The fundamental basis on which Location, Search & Naming (LSN) facilities in OSM work
  2. Why those facilities fail for a substantial part (40%) of the UK
  3. How to fix it

You need to know that the writer has been mapping for only 5 months, and therefore only part-understands what he is talking about. One (possible) advantage is that his is a fresh eye, plus he has the ability to think for himself. As the writer enjoys stories, much of this will be presented in that form.

On Thursday 9 June 2016 I began to map outside of my home patch in Nottingham NG3 and met the Boundary marker which, since 1877, has marked the Boundary Line between the City of Nottingham and Gedling, and also between NG3 & NG4. I was now heading for Carlton, Gedling.

One feature that had been common throughout my NG3 mapping was that LSN had consistently failed with OSM. When I was mapping close to St Anns OSM said that I was in Thorneywood, and so on. By the time that I reached Carlton I'd gotten the basic map methods under my belt & could pay more attention to the condundrum of the fact that when I was working in Carlton (a Suburb) OSM said that I was in Bakersfield (at the time a Neighbourhood, but now a suburb), or even Thorneywood (another Neighbourhood).

Practical examples can focus the mind, and this post is typical. I placed the Diary arrow in Highfield Drive, Carlton, but the result was: “Location: Thorneywood, Sneinton, Nottingham, East Midlands, England, United Kingdom”, which isn't even the correct District. That was just embarassing.

Eventually it became clear that OSM was giving precedence to Neighbourhoods over Suburbs, which seems perverse, and I was deep into conversations with Will & Jerry (my nearest active, senior mappers) on how to handle it all. One of the results of those conversations was Bakersfield being changed from a Neighbourhood to a Suburb, which helped a bit, but that was only a minor part of the truth. A clue was given when a commenter (somewhere) said wrt LSN that “areas are important, not nodes”.

On 16 July 2016 I met, documented & mapped Nottingham's Unparished Areas.

How Location, Search & Naming (LSN) facilities in OSM work

It starts with admin_level=10 BoundaryLine areas. If they do not exist, then OSM will do the best that it can but, as documented above, often fails miserably. If they do exist then, as longe as yur speling is gud, then OSM will be able to find your search item and/or locate where you are and/or name that locality accurately.

Why Location, Search & Naming (LSN) facilities in OSM do NOT work

Whilst there are ~10,000 Civil Parishes (CPs) in England (which is what an admin_level=10 BoundaryLine area is documenting), a very substantial area of the country is unparished (referred to as an “Unparished Area”) (see all the “unnamed areas” in the Civil Parishes page). I've spoken to a very helpful & knowledgeable lady at the Local Government Boundary Commission (0330 500 1525) (hello Joe) who, to my dismay, confirmed that Unparished Areas are the Black Hole of the Boundary world. It was ‘dismay’ because many mappers have a cast of mind which insists that, if the authorities do not recognise it, then neither will they. That means that they do NOT want an admin_level=10 BoundaryLine area to exist for the Black Holes, and that means that LSN will never work for those areas. Oh dear.

Locally to me, the cities of Nottingham, Derby, Stoke-on-Trent and Leicester are Unparished (plus my home town of Hull), as also are Arnold and Carlton (one non-parish) plus Beeston. Notice that the last two are each named, even though they (supposedly) do not exist. St Anns and Thorneywood are both in the City of Nottingham whilst Carlton is within Arnold and Carlton. Thus, none of those 4 neighbourhoods/suburbs was at that time within an admin_level=10 BoundaryLine area, and my assertion is that is the reason that LSN features of OSM were inoperative for them.

The previous paragraphs are mixtures of anecdotal & written evidence, as I did not realise at the time why it was going wrong, but much of it did get documented due to my diary entries. The following is fully evidential:—

Nottinghamshire Civil Parishes - names for unnamed areas: the location arrow for that diary entry is placed in Slab Square, Nottingham. I moved the arrow a tad on 2 occasions when the BoundaryLine setup changed to discover the effect. These are the three location results + the BoundaryLine setup that applied at the time:

  • (Original)
    Location: Nottingham (Unparished), City of Nottingham, Nottinghamshire, East Midlands, England, United Kingdom
    ‣ admin_level=10 name=Nottingham (Unparished)
    ‣ admin_level=6 name=City of Nottingham
    ‣ admin_level=6 name=Nottinghamshire
  • admin_level=10 relation removed
    Location: Lace Market, St Ann's, Nottingham, East Midlands, England, United Kingdom
  • “City of Nottingham” relation changed to admin_level=10;8;6
    Location: Lace Market, Nottingham, Nottinghamshire, East Midlands, England, United Kingdom
    Searching for 'Nottingham' in OSM gives:
    City Nottingham, Nottinghamshire, East Midlands, England, United Kingdom

Notes: The admin_level=10 relation was removed without consultation (as I understand it, this is considered by OSM to constitute abuse). Nevertheless, I took the opportunity to test out the effect of those changes, as shown above.

The Nottingham UA relation was changed by me to “admin_level=10;8;6” at 5am in the morning and returned back exactly as before shortly after completing the tests within the hour. That seemed a perfectly innocent action to me, but apparently not.

How to Fix It

All the evidence suggests that no admin_level=10 BoundaryLine area means no accurate LSN in OSM. The simplest fix to my mind is to enter a BoundaryLine for each Unparished area, but that is proving controversial. Even more controversial is my suggestion that, if folks want to discriminate between a CP and an Unparished area, then use designation=civil_parish for CPs & designation=non-civil_parish for Unparished areas. designation is an acceptable key for these folks, but both values are not, even though one non-standard value (and many others) has been promoted on a wiki for many years.

The main problem comes with Unitary Authorities (UAs). It is possible that, with a bit of tweaking, that the UA admin_level could be set to let it work. But maybe not.

Contra-Indications: Completing a recent Diary entry I set the pointer between Valley Road and Prospect Road. That location has an admin_level=10 area set. Saving the post, OSM said it was:—

Location: Thorneywood, Sneinton, Nottingham, East Midlands, England, United Kingdom

With Nominatim it seems, at times, that no-one actually knows how it all works. I've presented here my discoveries as I got my legs under OSM's table across the last 5 months, plus a simple method to fix it. My pessimistic belief is that no-one will be able to agree on a solution, and my ignorant, blundering efforts so far seem to have only provoked personal abuse and sleepless nights.

Parish Councils + Town Councils

The Ordnance Survey refer to a “Civil Parish (CP)” in their .shape files, but the Parliament Research Paper refers to:

  • Parish Council
  • Town Council
  • Neighbourhood Council
  • Community Council
  • Village Council
  • City Council

The above are the different styles that such bodies can freely adopt.

1894: Parish Councils Act : Parish and Town Councils first establishment.
1972: Local Government Act : source of modern legal foundation.

Powers: In theory Parish & Town Council powers are identical to those of a District. However, they mostly do not have the resources to do anything more than Leisure Services.

County Council: (admin_level=6) : Education, Highways
District Council (admin_level=8) : Bin collections, Cemetaries, Parks & Boundaries
Parish Council (admin_level=10) : (everything else)

Unparished Area (admin_level=??) : parish powers handled at the district level

Coda: The Scale of the Problem

Clearly, we need to know how much of the country is affected by this issue. I'll publish the full figures in a separate Diary entry, but here is the bottom line:

Parished: 11,329 Parishes; Average area/Parish=1,253 hectares; Total area=14,199,250 hectares (61%)
Unparished: 3,069 Parishes; Average area/Area=3,007 hectares; Total area=9,229,902 hectares (39%)

Mapper of the Month : Jorieke Vyncke (Belgium)

Posted by escada on 20 August 2016 in English (English)

Jorieke, a 28 years old Belgian, has spend a lot of time the past few years to support local OpenStreetMap communities all over the world. She worked on several projects in Africa, Europe and Asia to train people and to promote OpenStreetMap by local and international players.

Jorieke at the  Mapfugees in Duinkerke

Where and when did you discover OpenStreetMap?

I discovered OpenStreetMap at the end of 2010, "you will enjoy it", and YES ! I showed OpenStreetMap to my two brothers and together with them I mapped our village Wechelderzande Thanks to my student job as mailman, it was very easy, I knew half of the house numbers in the village by heart! Some time later, I discovered HOT, the Humanitarian OpenStreetmap Team, and Map Kibera. As social agoge, who had the ambition to work internationally and who was enormously interested in participation and spatiality, it simply had to interest me. My studies in 'Conflict and Development' gave me the opportunity to delve deeper in this type of mapping. I even got the chance to work for 6 weeks in Bangladesh for my master thesis. It gave me the possibility to talk with students and professors in architecture and spatial planning, the local OpenStreetMap community and a lot of people living in slums. And yes, it was them who really convinced me to use OpenStreetMap as a tool in humanitarian and development contexts. Precisely because they can put their neighborhood on the map themselves. After this project, everything went fast, a few months later I flew for the first time to Africa for the Eurosha project, in which HOT was one of the partners. And it never really stopped since then...

Do you use OpenStreetMap yourself?

Of course ! The apps OsmAnd and Maps.ME have "saved" me several times when I am abroad. You should see the faces of the taxi drivers in Bamako or Abidjan, when I can navigate them without problems to my destination. And when you show them the apps, their surprise is complete. "OpenStreetMap for taxi drivers", would make a nice little project :-) Those apps also give me confidence when I walk around in an unknown neighborhood, because now you know where you are and where you want to go.

Besides this personal use, I also often use OpenStreetMap for my work. For example, during my last project in Côte d'Ivoire, the complete logistic planning was based on OpenStreetMap. Check out one of the maps I made with Umap for this purpose.

I was very gratefull for HOT's Ebola activation! The western part of the Côte d'Ivoire is about perfect! With a few corrections by people that knew the region very well, we got the logistics running smoothly. Other parts of the country were harder, driving around for 40 kilometers to get in that particular village, was not uncommon.

GisDay 2015 met OpenStreetMap Mali

How and where do you map?

Most of the time I map were I am or were I have been. This means a lot in Belgium, but also in places where I had worked or had spend a vacation. Most of the time, I map the basics: roads, buildings, residential areas or points of interests. I leave more complex stuff such as relations or boundaries to other mappers. [JOSM](josm.openstreetmap.de) is indispensable for me. The main reason is that this editor does not require a constant internet connection! One can download data and aerial images, work for a few hours without network and electricity, and upload the data afterwards. This comes in handy when you are somewhere remotely in Africa! I am also a fan of less popular projects on the Tasking Manager. During a sudden natural disaster, a lot of attention goes to that one area at that particular moment, but there are a lot of countries with a forgotten crisis, such as Tchad, Mali or [South Sudan(http://www.openstreetmap.org/relation/1656678). There is a gigantic need for maps in those countries as well.

What is your largest accomplishment as a mapper?

Bangui! I lived and worked there for 3 months, participating in the Eurosha project at the end of 2012. Bangui is the capital of the Central African Republic (CAR). Before my stay, Bangui was hardly noticeable on the map. When I had to leave the country, it was there, and the data could be used by humanitarian organisations in times of crisis. The adrenaline was pumping through my body when we got a phone call in Cameroon from UN OCHA on the day of the coup when the whole city was looted, to ask whether we could help them. Of course we could!!!

At this moment there is a map of Bangui, which includes all health facilities and also in other parts of the country the map is improving via HOT remote mapping projects.

I am also very proud of the week I spend in Lubumbashi with Medecins Sans Frontiers (MSF): https://hotosm.org/updates/2014-04-01_a_week_in_lubumbashi_drc . Although I did not map a lot myself during that period, I instructed people to map for me :-) At the end of the week, around 15 students were walking around to collect data and we got tremendous help from remote mappers. After 4 days more than 60 people from around the world helped us. This synergy with Ivan Gayton of MSF, myself and the students in the field and the remote mappers, was the first seed from which the Missing Maps projects was born a few months later.

Data collection in Bangui

What is your motivation to map?

The community and the enormous passion of the people, which shows in small things. Some examples: Someone visiting a meetup with a bus that takes him 30 minutes more, simply because he had not mapped that particular route yet. The sparkle in someone's eye when her first edit appears on the map. The fire in the email discussions on the mailing lists, ...

But also how all this chaos, somehow coordinates to the result we see today on OpenStreetMap. A database build by ordinary people, but feeding economic development, and a key stone in some humanitarian projects.

OpenStreetMap is for me a great example of the inspiring "commons based economy" of Michel Bauwens.

Besides mapping, do you do other OpenStreetMap related tasks?

Since the spring of 2015, I am in the board of HOT. Besides that, I spend quite some time to answer all kinds of emails and to bring the right people in contact with one another. From time to time I do some translations, update the wiki and make a post on osm.be . I also speak on conferences, co-organise meetups and mapathons. At this moment I am busy with the organisation of the HOTsummit and the State of the Map conference.

To conclude, is there anything else you want to mention?

Do not be afraid, just make that first edit. Everybody can participate in OpenStreetMap, I am the living proof of that!

Waar en wanneer ontdekte je OpenStreetMap?

Ik ontdekte OpenStreetMap eind 2010, "je gaat dat wel leuk vinden", en ja hoor! Ik toonde OpenStreetMap vervolgens aan mijn twee broers en mapte samen met hun ons dorp Wechelderzande. Dankzij mijn studentenjob als postbode, was dit enorm gemakkelijk, ik kende de huisnummers van half het dorp gewoon uit m'n hoofd! Een tijdje later ontdekte ik HOT, het Humanitarian OpenStreetmap Team, en Map Kibera. Als sociaal agoog die ambitie had om internationaal te werken en enorm geïnteresseerd was in participatie en ruimte kon dat niet anders dan mijn interesse opwekken. Mijn studies Conflict en Development gaven me vervolgens de mogelijkheid om dieper te graven in dit soort mappen. Ik kreeg immers de kans om 6 weken veldwerk te doen in Bangladesh voor mijn masterproef. Het gaf me de mogelijkheid om te spreken met studenten en proffen architectuur/ruimtelijke planning, lokale OpenStreetMappers en vele sloppenwijkbewoners. En ja, het zijn zij die mij echt overtuigden van OpenStreetMap als tool voor het mappen in humanitaire en ontwikkelingscontexten. Net omdat je met OpenStreetMap je buurt zelf op de kaart kan zetten. Nadien ging het snel, enkele maanden later vloog ik voor de eerste keer naar Afrika voor het Eurosha project waar HOT één van de partners was. En eigenlijk is het sindsdien niet meer gestopt...

Gebruik je zelf OpenStreetMap in je dagdagelijkse leven?

Jazeker. De apps OsmAnd en Maps.ME hebben me al meermaals 'gered' in het buitenland. Je zou de gezichten van de taxichauffeurs in Bamako of Abidjan eens moeten zien als ik ze zonder probleem kan navigeren naar de plek waar ik moet zijn. En als je dan de apps toont, zijn ze vaak helemaal verrast. "OpenStreetMap voor taxichauffeurs" het zou nog een mooi projectje zijn :-) Ook maken de mapping apps me zelfzekerder als ik weer eens ergens (doelloos) rondloop op een plek die ik niet ken. Je weet waar je bent en waar je naartoe gaat. Daarnaast gebruikte ik OpenStreetMap ook al heel vaak in mijn werk. Zo hing voor mijn laatste project in Ivoorkust de hele logistieke planning af van OpenStreetMap. Check één van de Umap kaartjes die ik maakte maar eens: http://umap.openstreetmap.fr/nl/map/villages-a-enqueter-region-tonkpi-bleu-village-pmh_88667#9/7.3093/-7.8333 Ik was héél dankbaar voor HOT's Ebola activatie! In het westen van Ivoorkust is OpenStreetMap gewoon top. Met enkele correcties door mensen die de regio goed kenden, kregen we de logistiek vrij gemakkelijk geregeld. Andere regio's in het land waren beduidend moeilijker: 40 kilometer rond rijden om toch maar in dat ene dorp te geraken, het gebeurde verschillende keren.

Wat voor soort mapper ben je en in welke zone map je?

Meestal map ik waar ik ben en geweest ben. Dat wil zeggen in België, maar ook de plekken waar ik werkte of op vakantie ging. Meestal zijn het basisdingen die ik map: wegen, gebouwen, woongebieden of points of interest. Ingewikkeldere dingen zoals relaties of grenzen laat ik liever aan anderen over. Onmisbaar voor mij is [JOSM](josm.openstreetmap.de). Dit voornamelijk omdat deze editor geen constante internet verbinding nodig heeft. Je kan je data en luchtfoto's downloaden, voor een paar uur werken zonder internet en elektriciteit, en nadien de data uploaden. In Afrika kan dat al wel eens handig zijn! Ook ben ik fan van de 'minder populaire' projecten op de Tasking Manager. Tijdens een plotse natuurramp gaat veel aandacht vaak naar dat ene gebied op dat ene moment, terwijl er in landen met vergeten crisissen zoals Tjaad, Mali of Zuid-Soedan ook een gigantische nood is.

Wat is je grootste verwezenlijking als mapper?

Bangui! Ik woonde en werkte in het kader van het Eurosha project eind 2012 drie maanden in Bangui, de hoofdstad van de Centraal Afrikaanse Republiek (CAR). Bangui stond voordien amper op de kaart. Maar toen ik het land moest verlaten stond het er wel, en kon de data ook gebruikt worden in de crisis door de humanitaire organisaties. Adrenaline ging door m'n lijf toen we in Kameroen telefoon kregen van UN OCHA op de dag van de staatsgreep toen de hele stad geplunderd werd, kunnen jullie ons helpen??? Ja, dat kunnen we!!! Er is nu een kaart van Bangui, mét alle gezondheidsinfrastructuren en ook de rest van het land zijn we met HOT (remote) aan het mappen! Ook ben ik supertrots op mijn week in Lubumbashi met Artsen Zonder Grenzen (AZG) https://hotosm.org/updates/2014-04-01_a_week_in_lubumbashi_drc . Al heb ik zelf zo heel veel toen niet gemapt, ik heb de mensen eerder voor me laten mappen ;-) In Lubumbashi liepen er aan het einde van de week een 15-tal studenten rond om data te verzamelen, en ook werden we enorm geholpen door remote mappers. Na vier dagen hadden al meer dan 60 mensen wereldwijd ons geholpen. Uit deze synergie; van Ivan Gayton (AZG) en mezelf met de studenten op het terrein en de remote mappers, groeide het Missing Maps project enkele maanden later.

Wat motiveert je om te mappen?

De community en de enorme passie van OpenStreetMappers die vaak blijkt uit kleine dingen. Iemand die naar een meetup komt met een bus die er een half uur langer over doet, omdat hij deze buslijn nog niet gemapt heeft. De twinkeling in de ogen van iemand die zijn eerste edit op de kaart ziet verschijnen. Het vuur waarmee er soms gemaild wordt op de mailinglijsten. ... Maar ook hoe al deze chaos zichzelf op de één of andere manier coördineert tot het resultaat wat OpenStreetMap vandaag is. Een database gebouwd door gewone mensen die zorgt voor economische ontwikkeling, maar ook een stevige steen bijdraagt aan onder andere humanitaire hulp. OpenStreetMap is een prachtig voorbeeld van de voor mij toch wel inspirerende 'commons based economy' van Michel Bauwens.

Doe je ook nog andere dingen in verband met OpenStreetMap? Sinds de lente van 2015 zit ik in de raad van bestuur van HOT. Daarnaast spendeer ik heel wat tijd aan het beantwoorden van allerlei mailtjes met vragen en de juiste mensen met elkaar in contact brengen. Af en toe vertaal ik, update ik de wiki, doe ik een post op osm.be, spreek ik op een conferentie of organiseer ik mee meetups of mapathons. Momenteel ben ik ook bezig met de organisatie van de HOTsummit en de State of the Map conferentie.

Om af te sluiten, is er iets dat je de lezer nog zou willen meedelen? Laat je niet afschrikken, doe gewoon die eerste edit. Iedereen kan OpenStreetMappen, daar ben ik het levende bewijs van!

Defragging Fragged Streets

Posted by alexkemp on 20 August 2016 in English (English)

There has been an increased alertness to my changeset comments in recent weeks. I thought it reasonable, since I'm half-inventing words, to explain at greater length what on earth was going on.

I started mapping in March by entering house numbers & names onto the map & have continued doing that most days since. I've been using terracer within JOSM to do it, including associatedStreet relations for each house, something that terracer made easy. The team that maintain JOSM have been working hard to allow it to work under Java-8 (the dependency was previously on Java-7); however, many plugins (including terracer) are unmaintained and, as the chief developer informed me, they do not bother to check what effect their changes have upon any plugin.

Shortly after I started, version-32158 started crashing JOSM when certain options were selected and, shortly after, it was NOT possible to create a relation with terracer under any circumstances. That circumstance continues today, using the current-stable JOSM-10786 (terracer-32699).

This is how to create a new associatedStreet relation:

  1. Select your street ways + all houses
  2. From the menu, choose menu:Presets | Relations | Associated Street
  3. From the dialog, Enter the name of the street
  4. Press “New relation”
  5. (house members should get a ‘house’ role, whilst the street ways get a ‘street’ role)

That was fine, and it worked, but I only knew how to create a new relation, and not how to add new members to an existing relation. Consequently, and especially with big roads, the number of relations for each road began to grow. I was fragging (fragmenting) the street relations.

Eventually, I discovered how to add new houses to an existing associatedStreet relation. This is how you do it:

  1. Select the houses and/or street(s) to add to an existing same-street relation
  2. Switch on the Relations window (menu:Windows | Relations) or (alt-shift-R)
  3. Select the associatedStreet relation to add to and click on ‘Edit’
  4. The houses, etc. that you selected outside of the Relation Editor are now selected in the RHS window; click on the button to add them to the relation
  5. (optional) sort the relation
  6. Click to save

I hadn't done it deliberately but, since it was me that had fragmented so many street relations, It seemed only reasonable that it should be me that defragged them. Hence the changesets. I notified them one at a time so that, if something went horribly wrong, it would be easy to revert any individual street.

Project Map Pinedale - Completion

Posted by MRPockets on 19 August 2016 in English (English)

Project Complete

I have finally gotten around to finishing up the bits & pieces of Pinedale proper that I am aware were still unmapped (according to the goals I gave myself for this project). I believe now that I have succeeded in my stated goals!

Mapping Still Needed

Pinedale proper is extensively mapped (though of course there is much that could be added: sidewalks, more POIs, etc) but the outlying areas as still mostly unmapped (excepting roads). While I will continue to map the area as I can & have a desire to do so, I will not be putting much concentrated effort into it. If there are any other mappers in this area, I invite you to put some work into the areas that are still lacking.

Location: West Pine Street, Pinedale, Sublette County, Wyoming, 82941, United States of America
