Users by language

I am just an average guy who is fascinated by all crowdsourcing projects on the internet. I try to support as much as time allows - especially on OpenStreetMap and Wikivoyage.

My helpful toolsEdit

I wrote some small web apps, which are hopefully useful to some contributors.

Manual creation of district overview mapsEdit

The video below shows how to create dynamic district overview maps like in Kuala Lumpur or Amsterdam:

Create GeoJSON with JOSM and upload to Wikimedia Commons

Some additional explanation

In short there are two options to create a district overview map:

1a. only
Go to, draw the lines/polygons, give them the desired color and title. Copy the GeoJSON file and proceed to step 2. A certain disadvantage with this solution is, that you cannot merge nodes. So if you have 2 polygons right next to each other, they won't be perfectly aligned. With the solution in 1b this problem is nonexistent.
1b. JOSM & (shown in the video above)
Use JOSM to draw polygons as desired and export as .geojson. Some notes:
  • The export of polygons to .geojson only works as expected in JOSM, if the polygons have a describing tag assigned to it, which is normally applied to an area (e.g. landuse=residential).
  • You can assign the title tag to each polygon/line right in JOSM, if you don't want to do it in (e.g. title=[[Amsterdam/Noord|Noord]]).
2. Upload to Commons
Create a new map in Wikimedia Commons and paste in the GeoJSON created in 1.
3. Create mapmasks
In order to grey out the irrelevant parts of a district article map (example) you can paste the GeoJSON from 2. into the tool Mapmask <-> GeoJSON Converter to create the mapmask code.
