Ich möchste hier eine kleine Zusammenfassung der diesjährigen FOSSGIS-Konferenz wiedergeben um zum einen zum Ausdruck zu bringen, dass die Konferenz wirklich super war und (wie jedes Jahr) sehr viel Spaß gemacht hat und zum anderen um etwas Werbung zu machen damit nächstes Jahr hoffentlich noch mehr Leute aus der OSM-Community vorbeischauen und mitmachen.
Die Konferenz fand dieses Jahr in Salzburg statt und ging direkt der jährlich an der Salzburger Uni stattfindenden AGIT voraus. Dadurch ergab es sich, dass die FOSSGIS von Montag bis Mittwoch und nicht wie sonst von Mittwoch bis Freitag stattfand, und somit die Ausrichtung eines speziellen OSM-Sonntags ermöglicht wurde. Der OSM-Sonntag war ein wirklich tolles Extra und hat mir sehr gut gefallen! Da vor allem OpenStreetMapper anwesend waren, war das ganze noch etwas familiärer und man konnte sich noch besser über aktuelle Themen und Projekte unterhalten und informieren. Ich hoffe, dass sich auch künftig wieder eine Möglichkeit findet, solch einen speziellen OSM-Tag zu veranstalten. Wichtig ist, das er am Wochenende liegt, da dann einfach mehr Leute Zeit haben und sich nicht extra Urlaub nehmen müssen.
Michael hat im Blog eine sehr nette und vor allem treffende Zusammenfassung geschrieben. Ich kann auch die Vorträge dazu eigentlich alle empfehlen.
Zum offiziellen FOSSGIS-Programm gab es auch eine Vielzahl interessanter Vorträge und Gespräche. Ich habe selbst nicht alle angeschaut, möchte aber dennoch ein paar Empfehlungen abgeben.
Dazu gehört der Vortrag Jenseits von Mercator von Christoph und insbesondere auch der tollen Demo der Quincunx-Projektion. Die Vorträge Flächen und Kanten von Roland, die Bachelorarbeit von Nathanael Lang und Jakob Miksch' Masterarbeit widmen sich alle vornehmlich dem Fußgängerrouting und Routing über Flächen. Etwas das ich mir schon lange wünsche, aber leider bisher noch nirgends wirklich gut umgesetzt wurde. Aber vielleicht wird das ja demnächst etwas mit z.B. der Arbeit von Jakob. Zudem sollte man sich Frederiks Vortrag zu automatischen Edits und Importen ansehen: Damit man mal sieht, was alles für Scheiss importiert wird und warum die DWG (zu) viel Arbeit hat!! :-)
Am Dienstag gab es dann von Manuel Roth und Kollegen einen Vortrag zu Vector Tiles um deren Arbeit es wohl auch etwas Ärger mit Mapbox gibt. Der Vortrag ist auf jeden Fall sehenswert. Ebenso empfiehlt sich Serhan Şens Vortrag über den Leitstellensimulator. Er zeigt eindrucksvoll den hohen Aufwand für dessen Betrieb, zeigt aber auch, wie mit solchen Projekten neue Mapper gewonnen werden.
Am Mittwoch fand ich besonders den Vortrag OSM schön gemacht interessant. Der Vortrag war gut aufgezogen und die von Mark Padgham neu erstellten R-Pakete sahen sehr vielversprechend aus. Vielleicht doch endlich mal ein Grund die eigenen R-Kenntnisse zu verbessern! ;-)
Es gab sicherlich noch viele weitere interessante Vorträge die ich hier nicht erwähnt habe und ich habe bisher auch selbst noch nicht alle Vorträge angeschaut. Man unterhält sich dann eben doch öfter auch mal mit anderen OpenStreetMappern oder hilft dem Videoteam bei Schnitt und Kontrolle. Ich bin mir aber sicher das ich auch die restlichen Vorträge noch ansehen werde. Guckt selber einfach mal die Liste aller Vorträge durch.
Viel Spaß beim Anschauen der Vorträge und ich hoffe es bekommen dann noch mehr Leute Lust, nächstes Jahr eben doch auch persönlich aufzutauchen und sei es nur an einem "OSM-Sonntag".
This is a hobby. Using my pseudo corporation which name is lesmana corporation, i am trying to map all of my village building and other feature else, particularly feature thats inside and touch the boundary of my village districts.
wish me luck happy mapping to all of you
Wiki Loves Maps is a project that aims to improve the quality of geoinformation of articles in SQ Wikipedia and to articles in Wikipedia in other languages related somehow to Albania. The project started when some members of Open Labs Hackerspace (located in Tirana) reearched and found out that there are a few articles in Albanian language Wikipedia with coordinates. Secondary goals of the project are also (a) the increase of skills for existing Wikipedia and OSM editors through the improvement of content and (b) cross-involvement of the OpenStreetMap community in Albania with the Wikipedia community.
Personally I consider Wiki Loves Maps very important for the local Wikipedia community since there are not much articles will coordinates at the moment related to point of interest of different cities in Albania. Articles with geoinformation and coordinates get also displayed in mobile applications such as OSMand, which are widely used from tourists worldwide. As part of the project we are planning a number of edit-a-thons inside and outside our hackerspace in Tirana. You can find all the details of the project and ways to get involved here (Albanian article).
Close to where I live there is a small settlement (never more than two houses) which every local knows as "Krausens Mühle" (Krausen's Mill). Obviously this name is used since more then 230 years when one can believe these maps: Berliner Meilenblatt from 1790 (Krausens Mühle is at the top a little left from the center)
A mail I wrote to the company on 1st of October 2015 regarding these names and citing the sources above remained unanswered to this day.
In meiner Gegend gibt es eine Örtlichkeit/einen Wohnplatz, der Krausens Mühle heißt. Zumindest nennen ihn alle Leute so, mit denen ich darüber sprach. Dieser Name wird offenbar ununterbrochen seit mindestens 230 Jahren verwendet, wie diese Karten zeigen:
Das lokale Unternehmen, das die Haltestellen bewirtschaftet, sieht das nicht so eng. Das erste Foto, das ich von der Bushaltestelle mit deren Namen darauf machte, ist von ca 2010 und zeigt den Name "Krauses Mühle":
Eine Mail, die ich an dem 01.10.2015 mit obigen Quellen an das Unternehmen schrieb, blieb bis heute ohne Antwort.

Martin Dittus normally does this sort of analysis!
Just looking at our present counts of everything in #MapLesotho
We count nodes being created, edited and deleted. We have set up the count to feed out of the osm database, so anyone working within the polygon of Lesotho is picked up. Of course GeoFabrick only gave Lesotho "spatial sovereignty" in February 2015, so we have a year and a half of editing to look at here. This shows 824 people involved.
I like to cut off at 100 mappers. When you do that you see that the top 100 have done 97% of the mapping. The remaining mappers listed tend to have very modest contributions to #MapLesotho. The modal value of nodes is in fact 1. I have no idea what causes this, but when I click into their usernames I tend to see a mixture of once-off mapping, dormant accounts, while others are do appear to be active. Indeed, there are even some that I see involved in other HOTOSM and missing maps tasks. So regarding humanitarian mapping I guess #MapLesotho is like a holiday resort, a bit of a hotel to park your single node. And its not a high priority task, so that's ok isn't it...?
Between 50 and 100 is an interesting space. Most of the mappers here I have met and taught to map. They are mostly Irish schoolkids from Portmarnock or Basotho Planners. Mapping didn't really grab this group as their favourite activity, of course they can have up to 10 mapping days and over 10,000 nodes. But those that are not new are attenders, they sit back... others will organise the Mapathons. Others will map alone. They feel safe in the big group and have mainly helped the mapping by making the feeling of a flock. But when we get to the 50th mapper mark we still have have 94% of the mapping done by those above.
The mappers in the top 50 are a blend. There are far more Basotho people in this group. In fact I can see that 36 are Basotho, and 14 are not. Of the 14 around 7 are from Ireland, while the other seven are international crowdsource contributors who simply like #MapLesotho. However, these 14 are more likely to be at the upper end of the register. For example in the top 10 provide 75% of all the mapping, and as many as 5 are international, leaving 5 Basotho. Tshedy is a Basotho Physical Planner and is at the top of the tree for all of us all, but the next biggest Basotho mapper Lineo is 6th.
While its always good to know that such a large number of people are involved I am learning that quality control is best exerted with the top 50 people. The others help out - of course they do. Is every node cherished - of course it is. Is it all a caste system where mappers not in the top 50 can't get into the club - of course not! However, the end result is best affected by talking to the top mappers, engaging and even debating things with them.
Want to play with the top 100 data?
The helpful householder at 88 Main Street, Carlton pointed out the Benchmark on his house:—
Ordnance Survey Bench marks (BMs) are survey marks made by Ordnance Survey to record height above Ordnance Datum. If the exact height of one BM is known then the exact height of the next can be found by measuring the difference in heights, through a process of spirit levelling.
That neatly explains the BM numbers which you can find on old maps. In this modern Star Trek age, when anyone armed with a communicator (sorry, I mean mobile phone + suitable app) can measure their position & height above mean sea-level, the Ordnance Datum Newlyn is a touch out of date.
Unfortunately, I do not seem to be able to find a simple method to attach a Benchmark reference to a house in JOSM that will show on the map.
You will not be able to find a Main Street in modern Carlton NG4, as that is the name that the street had in 1876 when number 88 was Carlton's first Police Station (the road is called “Carlton Hill” today). The sole modern reference to it remains in the placard for the nearby Methodist Church, which is on the same street:—
Many thanks to Mr Bernard Leaper for his generosity in sharing the results of years of research with me. He tells me that the last Inspector was Inspector Marshall before the old Station was moved to it's current location (though not the same building) on Cavendish Road (when I surveyed it, the lady inside the Police Station told me that it was due to move again). The final use as a public building for 88 Main Street was in the 1950s as a Civil Defense Headquarters. Mr Leaper also finally answered my month-long search for the original centre of Carlton, which was Carlton Square.
Today, Carlton Square is both a retail area and also a street, but originally was Carlton town's centre, where the modern Cavendish Road, Burton Road, Station Road and Carlton Hill join. Like most towns, the square was originally faced with busy shops. Today, it is partly composed of brutalist concrete 1950s buildings, the side of a Tesco car-park & traffic, and most folks have completely forgotten it's original place as the heart of Carlton.
Wednesday 13 update:
I've moved the Carlton suburb node from it's position at the top of the hill to the old town centre (the actual place, as detailed above). Is there an actual ‘official’ Carlton town area/boundary? (and where is it?). If so, then the node can be deleted & replaced with an area, which would be much more satisfactory.
I've noticed in the past that the Normans tended to place themselves on the top of hills, whereas Angles/Saxons tended to live in the valleys or, at the most, on the side of hills. In any case, that is where Carlton has always been (at that crossroads), so that is where the OSM map should show it.
В 2GIS есть возможность посмотреть где находится вход. И конечная точка маршрута практически всегда заканчивается на той стороне дома, где находятся входные подъезды. Это очень важно! К примеру в Google маршрут обрывается прямо на дороге. А как подъехать к дому? - Ищи сам. Это очень неудобно. И еще! В 2GIS очень точные карты. Если бы это как-то использовать при развитии проекта OpenStreetMap, то был бы очень большой плюс для проекта.
Riprendo ancora questo tema.

devo verificare in OSM perchè sembra che si tratti del viaggio opposto (infatti la fermata iniziale 07002 è a Sant'Andrea. Da invertire l'ordine nella relazione.
Sistemato, posso elaborare con spreasheet...
Be' qua il lavoro comincia a farsi tosto e noioso... Perché non provare gtfs-editor? É open source, le procedure sono guidate e mi permette di creare da mappa, con un riscontro decisamente più immediato.
- Tengo utile la query che mi elenca le fermate e le relative coordinate
- creo un Agenzia ed una route con un paio di fermate cliccate a caso sulla mappa
- esporto un gtfs giusto per avere un template dove inserire le vere fermate della query
- adatto gli header del CSV ed importo il gtfs modificato. A questo punto ho tutte le fermate sulla mappa
- rinuncio alla query delle relazioni OSM, a favore del clicca su mappa la sequenza (trip)
Hoje resolvi mapear o Bairro da Cohab no Recife/PE. Estou colocando nome nas ruas sem nome e criando as ruas que ainda falta no Bairro!
Bom mapeamento para todos!
Note pour moi-même:
Adresse pour fond IGN:
Auf meiner github Seite habe ich einen Kurs zum Verarbeiten und Visualisieren von Geodaten in R.
Once upon a time I introduced lunarender map renderer here.
A month ago somebody asked on github if project is still alive. I told him project was suspended.
But this was impulse for later development.
I began to investigating how to solve major problems with my renderer.
GeoJson as rescue
I decided to switch to GeoJson as native input format. It will solve major problems with my renderer.
Firstly, there is nice nodejs app osmtogeojson. I will use it for assembling multipolygons.
Secondly, there are geojson-encoded vector tiles from Mapzen. I will use them to render large areas of maps in "tile by tile" fashion.
Planned features for v2
- cross-platform installation (aka no win binaries in linux zip)
- better command line parameters (inspired by Pandoc)
- better user manual (inspired by Pandoc again)
- multiple input formats (OSM XML, GeoJson, Mapzen tiles)
- multiple output formats (SVG, PNG, PDF, GeoJson)
- more map projections (probably via proj4)
- ability to render large area from vector tiles
- some improvements in rules syntax
I am also thinking about creating svg icon/texture editor. I used Piskelapp for my pixel-art-style icons, but it has no support for saving in SVG.
Feel free to ask some questions or suggest some ideas.
I have been mapping my hometown for quite a while now. This is where I am residing since birth and had my education in and around Gubbi. In Kannada language the term is related to a sparrow bird (ಗುಬ್ಬಚ್ಚಿ) . The town has a history of more than 150 years. This is the place from where I would love to start mapping.
Gubbi is geographically about 100km to the west of Bengaluru, the capital of Karnataka. The national highway NH-73 (previously NH-206) (Also known as Bengaluru - Honnavara Road) runs along Gubbi. The population of the Gubbi Town is 18, 457 as per Census 2011. The total area of the Town is 6.67 sq. km.
Status of map before putting my hands
This was how map of Gubbi looked before I started mapping
Most of the basic amenities and road networks in and around Gubbi was already on OSM. I thank OSM community for their contributions to the map around Gubbi.
The areas I worked on
Addition of missing POIs, buildings, roads and correction of errors in existing features.
Things I have added and improved
- Missing roads, tracks and pathways
- Added my home address and few residential buildings in the neighborhoods
- Added a railway track, platform and improved map of Gubbi railway station
- Added public buildings and POIs
- Added farms and fields around Gubbi
Few buildings that were added
Few edits on road network
Here are few of my additions
Close up of my edits
What do I foresee?
I always loved adding spatial data on to the map and have been enjoying mapping my hometown. For now I have added few features which I am intimately aware of. My plan is to add more details based on satellite imagery and local knowledge, and do a field survey with mapillary and/or field papers and improve the locality on OpenStreetMap.
I'd also welcome any comments from the mapping community on things that needs to be improved and also on what I've mapped so far, or tips for mapping.
The UK government provides Land Registry Public Data, amongst which is the strangely-named INSPIRE Index Polygons. That webpage says that they are “to help you locate registered freehold land and property in England and Wales”, and provides 348 ZIP files to do this.
~$ unzip -l UK/data/Abertawe_-_Swansea.zip Archive: UK/data/Abertawe_-_Swansea.zip Length Date Time Name --------- ---------- ----- ---- 68938 2016-07-03 09:36 INSPIRE Download Licence.pdf 128987164 2016-07-03 09:36 Land_Registry_Cadastral_Parcels.gml --------- ------- 129056102 2 files
I've just wasted a week of my life getting these files into a 48GB PostGIS db, only to discover that there is zero information in there other than GIS data. In other words, there are lots & lots of geometric polygons (very useful) and zero description on those polygons.
I was hoping to be able to find Areas for Borough Boundaries, and stuff like that. Oh spit.
Here is a quick run-through on how I managed to do all this. I had zero experience beforehand. Christian Ledermann, a Polish chap that adopts the name cleder & came to the June Nottingham Pub meetup to demonstrate his UK School import utility told me: “I have a little script that downloads everything and puts it into a postgis db (and shapefiles as an intermediate step): https://github.com/cleder/uk-landregistry ”. Christian's script is woefully short on documentation & details, whilst his UK schools utility would act as an efficient MITM attack vector on OSM (hoovering up usernames & passwords), and did not work for me.
The following has been achieved under a fully updated Debian 8.5. I actually used Synaptic for most installations, but that is GUI whilst I can more easily show apt-get instructions here. Look at the OSM Wiki for PostGIS Installation for more help.
Install PostGIS, PostgreSQL, GDAL, SubVersion + Fabric
sudo apt-get install postgresql postgresql-contrib postgis gdal-bin sudo apt-get install subversion fabric
Create the postgis working directory
mkdir -p uk/data
Get Christian's uk-landregistry script, and extract into the working dir
~$ svn co https://github.com/cleder/uk-landregistry.git uk_landregistry A uk_landregistry/branches A uk_landregistry/trunk A uk_landregistry/trunk/README.md A uk_landregistry/trunk/fabfile.py Checked out revision 2. ~$ svn -R ls uk_landregistry branches/ trunk/ trunk/README.md trunk/fabfile.py ~$ svn cat uk_landregistry/trunk/fabfile.py > uk/fabfile.py ~$ chmod +x uk/fabfile.py
Create the PostGIS db + user & place yourself as a superuser into PostgreSQL
~$ sudo -u postgres createuser osopen ~$ sudo -u postgres createdb --encoding=UTF8 --owner=osopen osopen_data ~$ sudo -u postgres createuser --superuser $USER
Activate PostGIS in that db
~$ psql --dbname=osopen_data -c "CREATE EXTENSION postgis;" ~$ psql --dbname=osopen_data -c "CREATE EXTENSION postgis_topology;"
Try to prevent authentication errors in the script (change any 'ident' or 'md5' to 'trust'):
~$ sudo nano /etc/postgresql/9.4/main/pg_hba.conf ~$ sudo /etc/init.d/postgresql restart ~$ sudo cat /etc/postgresql/9.4/main/pg_hba.conf | fgrep 'host ' # host DATABASE USER ADDRESS METHOD [OPTIONS] host all all 127.0.0.1/32 trust host all all ::1/128 trust
Now do the import (get_data) + place in PostGIS (import_shp)
~$ cd UK ~$ fab get_data ~$ fab import_shp
As you can probably tell, the learning curve for all of the above is intensely high, and Christian's scripts give no countdown as to their progress, and take forever to complete.
Was it worth it? Well, I learnt a lot. It gave me hands-on experience in using SubVersion, which was the item that tipped me into doing it. I have realised that SVN is just a method of storing files within a directory. All internal dir file manipulation needs to be done via SVN.
It took me a week of frustration just to be able to learn that. I'm now stuck with 48 GB of useless database files. So much for “Open Government”.
i was seen many lake and park,in (usa,canada,turkey) but some of to park and lake users not realy cerefule.i seen to much carbage, in to the that areas.maps making to hard but saving very hard and difficult,many people trying to make savings accound secure,park's and lakes also same and need to save to.you can thing about that parks and lakes nice bank,so do you have a nice account?
I've been mapping since 21 March, 2016 and have placed several thousand houses on to the Map in Nottingham NG3 & NG4 in that time. It is hardly surprising, then, that I've become a little obsessed with street names & house numbers & names. I did some research to try to settle all that inside me; so, here is a miscellany & glossary of facts about English house-numbers & street-names.
The first record of a house number in England is dated 1708
The British Postal Museum & Archive cites Prescot Street in Goodmans Fields, London in 1708 as the first recorded instance of houses being numbered rather than having a sign, or a name (Hatton’s New View of London (Google Books)). That fact indicates a significant change within the population. Above is a sugarloaf, in the traditional size & shape in which sugar was delivered to shops in the medieval period (the shopkeeper would break it up with a hammer before resale, which is how the tradition of sugar lumps came about). It is also the shape of the device that was hung outside of a shop to show that it was a shop. Very few people were literate at that time, so few could read a name, or even a number. Therefore, shapes & signs were hung outside of buildings to indicate what they were.
The appearance of house numbers is therefore a sure sign of the penetration of literacy through the population (as also is the popularity of the GPO — General Post Office — of course). The use of house numbers increased throughout the 18th Century, and in a completely unregulated fashion. No bureaucrat was going to stand for that...
Towns Improvement Clauses Act 1847 Enforces Street Names & House Numbers
This 1847 act is the earliest that I've been able to find, and is enforced at the local level (eg the Borough Council of King's Lynn and West Norfolk):—
Houses to be numbered and streets named
The commissioners shall from time to time cause the houses and buildings in all or any of the streets to be marked with numbers as they think fit, and shall cause to be put up or painted on a conspicuous part of some house, building, or place, at or near each end, corner, or entrance of every such street, the name by which such street is to be known; and every person who destroys, pulls down, or defaces any such number or name, or puts up any number or name different from the number or name put up by the commissioners, shall be liable to a penalty not exceeding £25.
Householders Must Show a House Number, or pay a fine
This is the next section of the same act as above. I cannot tell you how often this one is ignored in practice:—
Numbers of houses to be renewed by occupiers
The occupiers of houses and other buildings in the streets shall mark their houses with such numbers as the commissioners approve of, and shall renew such numbers as often as they become obliterated or defaced; and every such occupier who fails, within one week after notice for that purpose from the commissioners, to mark his house with a number approved of by the commissioners, or to renew such number when obliterated, shall be liable to a penalty not exceeding £20.
You can Call your House Any Name that you Like
As far as I'm aware, there is zero legislation on this. Certainly, the advice from the English Government is that you are free to choose what you want:—
Provided your home already has a number, then the property owner can add a name to it without contacting the council.
Councils have no powers over house names, the only guidance being that the owners should not choose one similar - or the same - to any other in the immediate locality.
The new name can be added to an existing postal address, but the postal number cannot be deleted from the address. The property name in this case will not officially form part of the property address; therefore the property number must still be displayed and referred to in any correspondence.
In my own observation, there has been at least one case where a road had house-names but no house numbers. That involved an “unadopted road” (a private road; the council has zero responsibility for maintenance of the road, which reduces annual charges immensely; it also normally means that the roads are difficult to drive down). Government, councils & the GPO do not like houses not having numbers.
I've also had one single instance in which a house had neither a name nor a number. The householder was reported to be a recluse & lived not very far from the “unadopted road” mentioned before. His house did not have a number, and none of his neighbours knew what it was supposed to be called. If he was in, then he did not want to come to the door when I knocked. I let him be & gave it an enigmatic name (I did not think that he would mind, or even notice).
