Jump to navigation Jump to search

This is the mapping between the OpenStreetMap (OSM) landcover classes and the FlightGear materials that was developed for the Central Europe custom scenery (line data) and the Caribbean custom scenery (both) (05/2020).

The OpenStreetMap wiki has more detailed information about the key-value pairs and combinations.
For more information about the possible FlightGear materials terragear accepts, see https://sourceforge.net/p/flightgear/terragear/ci/next/tree/src/BuildTiles/Main/default_priorities.txt.
