Mappers from Kolkata : Lets join hands

Posted by Suvajit on 5 February 2016 in English (English)

I planned to use OSM data for a transport oriented project for the city of Kolkata, India. I started few months back to find that there are large unmapped areas in OSM within the city itself. Also the mapping community activities have slowed down in last couple of years. I would like to call all mapping enthusiasts of Kolkata to join hands to ramp up the Mapping Quotient of the City of Joy effectively. Together we can make a difference.

First Entry

Posted by MRPockets on 4 February 2016 in English (English)

I've been a member of OSM for just under 2 years and I suppose I ought to start using this diary.

Project Map Pinedale

For the past few months, the majority of my activity has been targeted at the town of Pinedale, Wyoming, United States. This was (and still is) a very under-mapped town by most standards. So far, I have been able to map the majority of the businesses & buildings on main street (Pine Street). The remainder of the town on the map is almost exclusively roads at this point with some scattered buildings.

Goals

My personal goal for the next few months will be to map every major building (basically everything with the exception of some outbuildings, sheds, etc). Besides merely creating building outlines, I would like to tag each building with its proper address and any other information I can gather on it. Additionally, I will improve road mappings as I notice deficiencies. Ideally, I will be able to accomplish all this by the end of August.

Other

I will try to continue adding to my diary with status updates & possibly projected end-dates for this project.

On the odd chance someone else sees this entry & would like to contribute to this project, I would love to hear from you!

Good example of how we shouldn't map for navigation device

Posted by BushmanK on 4 February 2016 in English (English)

Recent question of some person, who uses maps for Garmin navigation devices, derived from OSM data, brought up a good example of tagging for navigator. He was dissatisfied by his Garmin navigator (actually, BMW branded Nav V) making straight routes instead of turn-by-turn ones in case, when destination is somewhere in the end of private road, tagged with access=private. He acknowledged, that Garmin Basecamp software works okay with the same map. Then he asked about proper way to tag roads, say, in suburban residential areas, where access is limited by locked lift gate, and where only residents have a key.

Several OSM contributors told him, that it is enough to put a barrier=lift_gate node on that way and to tag this node with access=private. Wiki suggests this as some sort of "intermediate" or "minimal" tagging method too (and obviously, it doesn't call it a "bad practice"). And it will help to avoid that issue of Garmin routing. But is it right and consistent?

First, access= key is intended to tell us, that access to tagged object is limited (or, otherwise, granted). So, tagging a lift gate with access=private literally means "this is a private lift gate", which only partially makes sense, since you still can approach it, but you can't operate (open) it.

Second, access regime of road is not necessarily created by physical barrier such as lift gate. It could have a sign. Or just a note. Or it could be limited by law. It means, we can't eliminate adding limited access tag to highway-tagged way itself completely, in any situation. Therefore, it makes that scheme with access=* on a barrier node obviously inconsistent.

Third, having some limited amount of data in bounding box around the point with access=*, it is impossible (without any additional tag, which should store the direction of propagation for this access rule along the way it belongs to) to find out, in which direction does this rule propagate. Another argument is that access rules for roads should be inherited from an enclosing territory, where this rule applies. But it's completely wrong, because there are access rules applied directly to roads, not to a territory, where this road is situated.

Indeed, it could be hard to tag every road behind the barrier with access=*. But that's another question - question of data completeness. Situation of incomplete tagging is normal for OSM, and it doesn't create any issue. But removal of access=* tags from roads does, because it increases an incompleteness.

So, that's why we should, ideally, tag roads with limited access tags and avoid relying on barrier node. Especially, if this tagging method is inspired by an attempt to compensate bugs of certain navigation system by changing data for it.

#MapLesotho Trip - 05th-22nd Feb - Follow along on snapchat

Posted by DaCor on 4 February 2016 in English (English)

tl;dr follow me on snapchat to see what the #MapLesotho folks get up to. Same as my twitter - dacor_ie

Very shortly I will be heading back to Lesotho for 2 weeks with DebigC and RustyB as part of #MapLesotho which is being supported by Action Ireland Trust and Fingal County Council.

This will be the final trip so during our time there, the activities will be much more focused on the long term sustainability of the project. Some of our main goals will be

  • Increase the general level of expertise (think: relations etc)
  • Data curation (KeepRight, OMSI etc)
  • Data analysis (Overpass, QGIS)
  • Train the trainer
  • Growing the community

We're also planning a monster Mapillary drive while we're there so I'll be including many photos and videos of Lesotho itself. You can see some from last years trip here

We will also have Oscar from Mapillary coming along to give a masterclass or two on using Mapillary.

If you are in anyway curious about what we're doing, I'm going to be using snapchat a lot while I'm there, in particular, creating ongoing "stories". These will feature snippets of the training, photos, interviews etc (though Im not sure how well the interviews will work given the limitations of snapchat) but it will also feature some of the downtime and general chats among the #MapLesotho folks. I'll be talking to a lot of the local mappers and covering some of our trips to govt agencies as we look to get data released for use in OSM.

If there are questions you'd like to see answered, I'll be taking those also. I have a list of questions myself, but it would be great to hear from others as there will be many things I simply won't think to ask about.

So yeah, follow me if this interest you :)

An attempt to geocode the list of schools from Dept. Ed. leads nowhere

Posted by rorym on 3 February 2016 in English (English)

In the UK they are doing a quarterly project to map more schools and there is a list of schools in Ireland from the Department of Education, but that only has addresses, not locations.

I thought I'd download that file and throw it at Nominatim and see if we can't geocode those addresses, and have something to work with. I thought with all the mapped townlands, that Nominatim might be OK at some of the rural addresses.

The results are not good.

Nominatim returns a bounding box for a result. Here's what happens when you try to geocode all the primary schools:

ireland

The big boxes are where nominatim was only able to get the county. You can see that many other boxes are just around towns and villages. Nothing more detailed than that. The map might as well be a map of "Counties and Towns of Ireland", which is useless for locating schools.

An example address is "SCOIL NAOMH MICHEAL,SNEEM,CO KERRY". It's no surprise that Nominatim cannot get any more accurate than the village of Sneem in that case. The other school in Sneem, SCOIL EOIN,TAHILLA,SNEEM,CO. KERRY, is hardly more accurate.

The code is in the "ie-schools-geocode" repository on our github Run "make install primary-schools-areas.shp" to generate the data. The geocoding is done in "geocode-single.sh"

That image is based on the shapefile in primary-schools-areas.zip. If you don't want to generate the data, you can just download it directly from github. By using the Open Data plug-in you can open it in JOSM.

Unfortunately, it looks like the schools list database isn't very useful for mapping all the schools.

Irish addresses, eh?

New GitHub Repository for OpenStreetMap Ireland code

Posted by rorym on 3 February 2016 in English (English)

OSM is a mapping project, but sometimes people write software to do stuff with OSM. Irish Townlands is one example of this. And that code (like much in OSM) is open source (see it here), and I use Github, since it's so popular for open source.

So I set up a Github organization for us! Here: OpenStreetMap Ireland If you're a Github user, feel free to join (on-line, or contact me and I can add you). I've already transferred the townlands.ie source code there. Feel free to transfer any other projects on github there.

Method of dealing with traffic signs, on islands in, and by areaised highways

Posted by Govanus on 2 February 2016 in English (English)

I copied this into my userdairy to make it easier for people with questions about my use of traffic signs on island on areaised highways to find my reasoning. It was writen in responce to someone stuggling and deleting and modifing them stating as part of the conversation:-

I've corrected two of them, the last one is here: http://www.openstreetmap.org/changeset/36931147 Please read again http://wiki.openstreetmap.org/wiki/Key:traffic_sign regarding the use of highway=traffic_sign on a way / node and see this changeset

http://www.openstreetmap.org/changeset/36875633

I think they had some fixed rules based on pre areaised uses that needed to be adapted to make sence of areaised highways https://wiki.openstreetmap.org/wiki/Proposed_features/area:highway https://wiki.openstreetmap.org/wiki/Proposed_features/area_highway/mapping_guidelines <--This is a new page I just found and am yet to study (ie not read before below was written...) https://wiki.openstreetmap.org/wiki/Proposed_features/Street_area <---This to also has new parts I'm yet to study too (for the same reason)

Comment from Govanus less than a minute ago

this sign was a very large direction sign. Somehow this needs to be a relation and not a phiscial way according to:- http://wiki.openstreetmap.org/wiki/Relation:destination_sign which is confusing to do to a real object rather than a virtual sat-nav indicator. there seems a lot of confusion possible till you realise that there are two functions of defining and indicating traffic signs in OSM Function 1: Alert the navigation system that a traffic rule is in action in a place or part of the road. Function 2: To indicate the location of street furniture used to make a physical sign displaying infomation to road users.

In simply mapped areas using a single way for everything then tags fit to way sections for function 1, and a point, with point specific tagging, carries function 2. Its been debated wether the point goes on and into the way (as all is 1-dimensional) or by the side like a more 2-dimensional form. The obvious over sign has hight seperating layering style tags to avoid confusion.

Now in more complex and more detailed mapping used for small area rendering like doorway approches etc meny line features gain full areas and it is logical to make point features of flat objects into lines carring the same tagging to give the same meaning especialy when signs become 10 meters tall and twice the width of the sidewalk like on the southen bypass. there are also box bolard signs used along this road when the flat ones where crashed into that was a cheap replacement. they may apper as tiny squares after being areaised the four faces can carry different signs when needed too (though I don't think the replacement one here dose and carries a non-sign on one side a black rimed white circle).

The function1 role for the traffic_sign UK:610 is given by forceing a split of the routing line at the correct spot to obay it, in an areaised highway. Remeber that the road now has lots of width as well as length and the routing line needs to follow the middle of the carrage way and not run over the sidewalk lamps and poles just drwan in the middle of the road, and this is the natural way to guide cars and busses past the features too (when some one measures the lane width changes and gives it in lane features it will make more sence too that lorries can take a staighter course but the routing line needs to fllow the middle for the logic of so meny other tags that get dumped on it. so that's why I drew them as I did. reading the wiki still dosn't seem to put this into question (especialy if you take the licence to convert points to ways when converting ways to areas when this make most sence when scaled to the phisical feature (ie the same size as real life)

The problem with this direction sign (in http://www.openstreetmap.org/changeset/36931147) is that direction signs don't commonly carry a common referance standard-drawing number in the pointed too offical traffic_sign manual because the signs a composed on a custom to site basis following some layout rules on stuff like spaceings and line widths and angles etc. So the function 2 tagging so far seems absent as only the function 1 seems covered so this sign needs to be here to be added to a form of more virtual sign defined here:- http://wiki.openstreetmap.org/wiki/Relation:destination_sign possibly as a new role type of physical sign board or something...

The sign contains sub signs too as well a very long winded textual execption list that will probably need a lot of special use of clausual tags (more common to parking) on top of this there is question make about the intergation this with lane tagging and/or diffend marking as although these are ghost lanes only the tagging for laneing carries a lot of this infomation on lane use and possible extions of the inclusion of detination tagging to complement this signs intentions, this is fitting more of the function 1 role. Finally the question of how to intergrate possible lane features that may be drawn in future into any relation for http://wiki.openstreetmap.org/wiki/Relation:destination_sign Is another question that will probably be answered as a yes included.

As I had run out of time for this doing the other 100 features needing offset correction I drew a simple sign board so it could at least be used for function 2 pedestrian navigation uses on the sidewalk (like "oh yes I'm here; because overthere's that huge sign shown on my map"). Also others might feel like finishing the puzzel for me as it wasn't finished.

Belgian Mapper of the Month: ponci4520

Posted by escada on 2 February 2016 in English (English)

Stefan is 28 years old and just finished his studies in resource and sustainability management (Joint Degree for Sustainable Development). Right now, he is looking for a job. He uses OpenStreetMap not only on a daily base for personal use, but also for his university research in order to visualise the distribution of cultural resources in cities. In future, Stefan would like to learn how to build his own map layers to show otherwise invisible buildings and infrastructures.

How did you discover OpenStreetMap?

The first time I heard about OpenStreetmap was at university. It was also mentioned in an edition of Arte, titled "Le dessous des cartes". But I only really started mapping after participating in a conference on the use of maps for the visualisation of sustainable economy and community initiatives. This initiative, called Transformap, hopes to produce thematic maps based on OpenStreetMap. After this conference, I took part in a monthly meeting of the OpenStreetMappers user group in Graz, Austria - where I was studying at that time. It is a very active group. Unsurprisingly, Graz is very well mapped. That motivated me to participate, so I started to map my own area, Hesbaye.

Do you use OpenStreetMap?

I spend a lot of time looking at maps. There is no other media that helps to understand, discover, or rediscover an area as well as maps. Maps also have the enormous potential to participate in the development of an area. I also have a smartphone with an OpenStreetMap navigation application, called OsmAnd. I use that app for navigation as well as an "ordinary" map of the place that I am visiting.

What kind of mapper are you?

Until now, I mostly did remote mapping in the area where I live: Hesbaye in the Liège province. But slowly, I started to follow some roads and visiting nearby areas to compare the map with the reality. I really like to discover new places thanks to OpenStreetMap. I do not have a real speciality, but by mapping my village, I learned a lot, especially concerning historical buildings. Since I want to show this patrimonium to others, I focus more on this topic at the moment.

What is your biggest achievement as a mapper?

Mapping the village I come from, though that is more like a never-ending marathon than an achievement. When I started, the Hesbaye region was barely mapped. However, nowadays, I notice that there are more and more mappers active in this area. Although I only contributed part of the data, I am very pleased that the map is getting more and more details.

How can we motivate more people to contribute to OpenStreetMap?

By organising Map-Jams and or workshops, e.g. in the Re_lab in Liège. By giving introductions to new mappers and teach them how they can use the different tools (JOSM, GPS, data imports) By organising regular meetings (once or twice a month) for mappers. By making a brochure with information for public services, companies, NGO's, computer scientist, etc. to promote the use of OpenStreetMap.

What is the strength of OpenStreetMap?

OpenStreetMap proved itself a couple of times to help people in need, e.g. after the earthquake in Haïti, or more recently during the ebola outbreak in West-Africa. The humanitarian intervention was more effective because the area was mapped by volunteers. The major asset of OpenStreetMap is without doubt its "open source" character. It is de-facto a common asset that belongs to humanity: everybody can participate -- of course you need an internet connection and a computer. Nevertheless it remains accessible for a large group. Those values are important and provide an alternative paradigm for the mantra of growth and commercial gain. I also believe that OpenStreetMap is a nice example of bottom-up internet organisation.

What is the biggest challenge for OpenStreetMap?

Exactly this internet governance. Unfortunately there are more and more examples of increased top-down control on the internet (for security reasons, economic issues, etc.). As often, there are good arguments for both sides, but I am convinced that open source software proves that the internet is a collaborative project that is for the benefit of all.

Anything else that you want to mention?

OpenStreetMap is really not difficult. It is a community with a lot of passionate people who use patience and enthusiasm to help anyone who wants to get their head around open source software. You can start by exploring the different OpenStreetMap maps and the rest will happen automatically!

Improving the road network coverage in Myanmar

Posted by Jothirnadh on 2 February 2016 in English (English)

Myanmar is witnessing an unprecedented growth in international tourist arrivals following major democratic reforms since 2011. On OSM, around 70,000 kms of roads have been mapped so far, or roughly 42% of the total reported roadways.

Most of the major highways (motorways, trunk, primary, secondary and tertiary roads) are well mapped in the major cities of Yangon, Mandalay and Naypyidaw, but there are a lot of missing residential and unclassified roads visible in the imagery. Over a period of three weeks, the Mapbox data team was able to add a total of 7,690 missing streets, out of which 2559 and 5131 streets were added in Mandalay and Yangon respectively.

yangon changes Missing streets in Mingaladon locality in Northern Yangon

Full map of all objects added or modified by the Mapbox data team.

Issues we faced

  • Lack of an active Myanmar mailing list or forum made it difficult to reach out to the local mapping community for collaboration.
  • Identifying the streets in densely populated places is difficult because of the buildings and thick tree canopy. Lack of GPS traces in these areas also hampered the process to add missing roads.
  • There is a lack of road network classification guidelines for Myanmar in the OSM wiki and the general highway classification guide was used for this purpose.
  • Most roads that were previously added seem to be from lower resolution imagery and required cleanup.

How you can contribute

  • Prepare an OpenStreetMap wiki for the road tagging classification in Myanmar similar to Indian roads tagging classification.
  • Community members can engage in contributing to other cities of Myanmar by adding missing roads.
  • It would be good if local mappers can add more GPS traces so that we can add the roads covered under canopy and buildings.
  • Community members can also review our edits and give feedback.

Create "Proximity Alert" for Garmin devices

Posted by Humitos on 1 February 2016 in English (English)

I've trying to create "Proximity Alert" for my Garmin devices for more than 6 months and I couldn't yet. I will detail the steps that I'm following so maybe you can give me a hint on where is my mistake:

  • Download data from geofabrick:

wget -c http://download.geofabrik.de/south-america/ecuador-latest.osm.bz2

  • Uncompress file

bunzip ecuador-latest.osm.bz2

  • Filter data to get only "traffic_calming=bump" (that's what I'm interested in):

osmfilter ecuador-latest.osm --keep= --keep-nodes="traffic_calming=bump" > ecuador-traffic_calming.osm

  • Create "Proximity Alert" with GPSBabel:

gpsbabel -i osm -f ecuador-traffic_calming.osm -o garmin_gpi,alerts=1,proximity=50m,speed=15kmh -F ecuador-traffic_calming.gpi

  • Copy this file into my Garmin device. It recognices my file but when I pass trough the POIs it doesn't generate the Sonor Alarm.

Do you know what I'm doing wrong?

Just added humps

OpenStreetMap POI finder

Posted by ruthmaben on 1 February 2016 in English (English)

We recently built this new tool which shows all amenities in a given area or between two points by dynamically spooling amenities using the overpass API. During the initial stage of the project, my initial though was just to have a POI map for Bengaluru but, we landed up building a map which shows POI's around the world.

Check this out - POI finder using OpenStreetMap data, it's a great outcome!

poi2

Map Features:
  1. Find POIs within a radius of 1km for any point on the map.
  2. Highlights all POIs within a radius of 1km for a route between any two points on the map.
  3. Filter POIs based on type.
  4. Using the Geocoding API, you can go to any place in the world and place a marker and it generates a buffer between the points.

Mapping Andhra University College of Engineering (Andhra Pradesh, India) using Field Papers:

Posted by nammala on 28 January 2016 in English (English)

Hello OSM mappers,

I ‘m new to OSM community and this is my first diary post in which I want to explain my mapping experience in using field papers

As a part of mapping using Field Papers for which I selected an area in my neighborhood (Visakhapatnam), I have chosen Andhra University college of engineering. The main reason for selecting this region as area of interest (AOI) is, I had done my bachelors from this University and also it is not yet mapped in OSM.

The general idea was to micro-map this area using field papers by identifying the number of missing buildings,roads,hostel blocks,canteens,shops,paths,tracks,statues,gallery stands,layout maps etc. For this, I printed the field paper copy (which consists of already mapped OpenStreetMap data) of the selected area and went to the field for collecting the missing data. It was very interesting to go to the field carrying the field papers, pencils, erasers etc. Basically, it was my first experience to survey in this manner because previously I had carried out survey using instruments like Total station to collect the data, go to laboratory for analysis and finally make edits to prepare a map. So, it’s a different kind of exposure for me to survey using field papers. Then I started going through the area and I have drawn sketches on the paper of particular buildings and gave numbering to that so it will be easy for me to identify while mapping, and I carried out the same procedure for rest of the area. It approximately took 2 hours for mapping the entire University. Mapped Field Paper Uploaded

After completing the survey mapping I scanned the mapped field paper and integrated it into the digital environment i.e., JOSM using the field papers plugin. I used scanned field paper as one of the base map above Bing imagery for reference while editing, which made my work much easier in identifying the AOI’s.

In this way I completed mapping Andhra university college of Engineering (AUCE) using field paper procedure. Thanks to Mapbox for assigning me such a skillful task and giving me the exposure to this kind of open mapping. I would really appreciate the OpenStreetMap community members if they can review my work and give their valuable comments or suggestions in which I can improve further. Final Map

Lima maps updates

Posted by Diego Sanguinetti on 26 January 2016 in English (English)

Hi all! I'm making a few updates on the city of Lima (Peru). In this city I did some contributions from GPS traces with notes to improve the city and reduce risks on the streets. This information continues to grow over time and can compare from this website.

Main

  • Improve the Pan American route (in Spanish: Panamericana Norte and Panamericana Sur; Reference PE-1N, alternate tracks and the corresponding exits)
  • Improve the Expressway (Vía Expresa) of the Costa Verde (which implusor was Ernesto Aramburu Menchaca with an avenue that leads his name in Paseo de la República). You can access the Armendaríz exit to connect the two highways.
  • Add information from districts: Los Olivos (including speed bump or sway), Comas and Rimac. About center of Lima I would add buildings.
  • Improve information continues for the Panamericana malls (some are pending).
  • Built tolls Pan American Industrial Separator with a limit of 10-20 kph. They include specified lanes for trucks and private light vehicles. See: https://www.openstreetmap.org/changeset/36671770

Additional

  • Add bridges (on the highway), pedestrian crossings and traffic lights.
  • Add neighborhoods (pending).
  • Add other places as hotels, parking lots, cinemas and restaurants.
  • Information to sports village of Callao (pending).
  • Added the pedestrian tunnel in Los Alisos.
  • Added features at the Jorge Chavez International Airport. For more information you can see this directory website.
  • Added center speed limits in this sector and to specify route time in Chorrillos map.
  • Considering the rigid area (zona ríginda) in Caquetá Avenue by the townhall. Information next stage was also added.
  • Fixes names and speed limits in the district of Pachacamac. In the future, according to El Comercio, It will be a commercial place.

Planned or under construction

Highlight the most important and that may affect the traffic of the city:

Please note that I'm adding information from other cities as accurate as possible and that can take a long time. If there are problems of translation of the original note you can do it in the comments. Cheers!

Myth of Newbie

Posted by BushmanK on 26 January 2016 in English (English)

Quite often you can read a reference to newbies in discussions of almost every aspect of OSM project. Someone could use that reference to say, that something is too complicated. For example - certain tagging scheme. In other cases, it is used to motivate someone, like, "you'd better translate that Wiki page, otherwise, newbies will not understand ..."

Actually, only a few references like that making any sense. Usually, it's nothing more than demagogic method to convince others. And here is why.

For example, in marketing people conducting studies, tests, using focus groups and panels to learn about target group of certain product, service or public statement. Even after that, they are not completely sure about results. And here goes John Smith, who indirectly claims, that he knows how OSM newbies think and so on, when he refers to them. No, he knows almost nothing.

There are only a few statistical studies, showing basically only one thing: spread of amount of edits (statistical or geographical). But there is no studies of behavior. I completely understand, that it's really hard to conduct a study like that, I don't even claim that I know how to do that. But what I'm trying to say, is that referring to newbies does not make much sense without it. Intuitive "knowledge" is not a knowledge at all.

Indeed, some people (only a few of OSM contributors, actually) have certain experience with newbies because they organized mapping parties or workshops. But is that empirical knowledge universal? Most likely, no.

For example, HOT volunteers have different motivation from people, who want to improve/fix map for their navigation device.Those who want to "help everybody at any cost" (importers of illegal data) have completely different motivation too. Lack of skill of reading in English or German also changes the situation, and if combined with overestimation of this skill, makes a disaster for translations.

Digging through these cases, it's easy to conclude, that only a fraction of issues, usually attributed to newbies, are actually linked exclusively to them. There is another term - amateur (in negative meaning, like, "one, who knows not enough to do certain job well and who doesn't really want to learn"), which describes the source of real recurrent issues, because it's quite hard to convince experienced amateur to change his attitude and a manner of work.

Obviously, newbies have to learn to make usable contributions. And it will eventually turn them into confident mappers, who understand own level of competency. In general, being regular people, they don't need any special treatment like if they were people with special needs. While many references to newbies include something, that renders them as extremely shy individuals. Likely, in cases like HOT projects, it makes some sense, because motivation of helping developing countries could attract those who are barely computer-literate, while self-motivated geeks in the rest of OSM are of different kind. But the whole OSM project is not equal to HOT and is not a subordinate of it. So, treatment should probably be different.

My claim is that currently Newbie is a mythical creature, that serves for rhetorical (demagogic) purposes. Its imaginary character is ridiculous: shy, illiterate, clumsy, stupid, incapable to learn, emotionally unstable and fragile, aggressive, ignorant, but in the same time - precious and very important for further OSM improvement and development. These epithets are not my fantasy - I took it from different statements, where reference to newbies was used for reasoning. Telling about it, I want to call for an active skepticism towards any statement like that.

personal electrical location info links

Posted by Govanus on 26 January 2016 in English (English)

these are some links I may use to help with cross-refenced data checkeing about the electric supply in areas I map the mapsdon't show the smallest voltage substations as they are very numourus and I guess may be semi-bypassed on a back feed.

In the UK verious enviromental based iniciatives have seen the need for the uk electrical distribution network that had once been organised with a top-down economies of very large approch start to be able backfeed for people originaly just supplied to one of these pages shows that current spare capacity to achive that for a new generator. Of course SSE will probably provide more capacity if requested with potentialy network enhancement costs which could cost more than a basic backfeed as well as the addtional time for new cables,trenches,towers and transformers to be built into the system. The other is a map of declared power cuts, small ones happen a lot from oftern from things going on around infrastucture like digging and things simply bashing into overhead lines, etc. the effect of cold weather is designed into the system but things not design to handle high winds like cars, trees and rubbish bins can crash into strained lines during high winds as if hurled by a battury of catapults in an anchient battlefield. Floods also cause headaces but works are underway in some places to impove isolastion from flood water through rasing or encapsulation.

A global map of all HOT contributions

Posted by dekstop on 26 January 2016 in English (English)

I've tweeted versions of this in the past (Feb 2015, May 2015), and used it in talks. Here's an updated version with data up to 13th January 2016.

In total this covers around 120 million changes to the map, by almost 20,000 contributors across 1,000 projects. This required an estimated 165,000 hours of volunteer work! There's a monthly breakdown of this activity in this Google spreadsheet: "2016-01 HOT activity timeline".

Global map of all HOT contributions

I'm keen to do an animated version at some point! Also, could a cartography geek please recommend a suitable projection for this map? Atm it's just the default WGS84, with apologies :)
