Ortsfarben

Ortsfarben is a map based tool that creates a postcard showing the landuse distribution in your neighborhood. The browser application uses Berlin’s landuse open data. By zooming in and out you can pick a location within Berlin and position it inside the circle. Ortsfarben then maps the individual areas onto a tree map diagram. You can print the resulting motive as a postcard and share it!

Or as GeoJSON:

You will need to convert the data to GeoJSON format and convert it to the EPSG:4326 projection if you want to create the tiles for the map .

Tile Creation

The tiles were created with tippecanoe by running the following command:

tippecanoe --output-to-directory ./tiles '--use-attribute-for-id=id' --no-tile-compression --force -B 13 '--minimum-zoom=10' '--maximum-zoom=13' ./alkis.geojson

Your input data has to be in GeoJSON format and in the EPSG:4326 projection.
