Röntgen is a
- simple Python OpenStreetMap renderer,
- set of icons,
- and map styles.
Project source: GitHub page.
The idea behind the Röntgen project is to have a possibility to display any map feature represented by OpenStreetMap data tags by means of colors, shapes, and icons.
Röntgen is primarily created for OpenStreetMap contributors. Suppose, you spent time adding colors for building walls, benches, and shelters for bus stops but they are not represented on the standard tile layer. Röntgen helps to display all changes you made.
Nevertheless, the Röntgen map generator can generate precise but messy maps for OSM contributors as well as pretty and clean maps for OSM users.
