By far the easiest way to get this data is to download shapefiles from the wonderful [http://mapserver.flightgear.org MapServer]. The MapServer lets you download the shapefiles for any selected scenery area. Click on the "Download Shapefiles" link (or go direct: http://mapserver.flightgear.org/download.psp). Enter in the bounding box of the scenery you want to generate, select the type of shapefile data you want, and click download. | By far the easiest way to get this data is to download shapefiles from the wonderful [http://mapserver.flightgear.org MapServer].

'''Layer differences''' | |||
* '''v0''': global coverage, low detail. This is "the last resort", but unfortunately it is the only layer that covers the entire world. | |||
* '''cs''': it is v0 with some contributions someone did in the past. Get this instead of v0. | |||
* '''v1''': only parts of some countries available, higher detail than v0. | |||
* '''clc06''': European '''only'''. Very high detail, this is the preferred choice for an European country. | |||
* '''osm''': global coverage, high resolution but very low detail. This means: if you are interested in an area out of Europe and forests are defined in OpenStreetMaps for your area, this is going to be the best data source. If forests are not defined, you will get a dull, neverending DEFAULT landclass. OSM provides the best coastline and I encourage you to use this coastline even in Europe.

Download each shapefile into a seperate (!) <tt>data/shapefiles/...</tt> directory. So, for v0_landmass, you would end up with <tt>data/shapefiles/v0_landmass/v0_landmass.shp</tt> etc. | Download each shapefile into a seperate (!) <tt>data/shapefiles/...</tt> directory.
