CORINE to materials mapping

From FlightGear wiki
Jump to: navigation, search

This is the mapping between the CORINE landcover classes and the FlightGear materials that was developed for the Custom France Scenery, updated with the definitions used for the Central Europe custom scenery (05/2020).

See also the OSGeo wiki for an attempt at normalizing the landcover types (but the correspondence with FlightGear materials is not straightforward there).

See this illustrated nomenclature for details about the meaning of the CORINE classes. 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.

Note about Airports

AirportArea, generated by genapts850, will partly override the Airport landclass. However, it is still suggested to build it as to avoid discontinuity (i.e. "holes" filled by Default material) between the airport boundaries defined in the apt.dat file and the surrounding landclasses.
