OwnHomeMap cartography reference library
This library documents what the OwnHomeMap renderer requests from map sources, how received features are classified, and what a poster cannot establish. Each reference separates product behavior, visual choices, and source-data limitations.
What this library covers
- The path from source data to the poster render.
- The mapping between road tags and visual levels.
- The inclusion rules for water bodies and green spaces.
- Coverage, update, and licensing limits.
- How to report a source-data or rendering problem.
