For Texel this is 31U, north of the equator, so we choose <tt>Projected Coordinate Systems > Universal Transverse Mercator (UTM) > WSG84 / UTM zone 31N</tt>. Always select 'WGS84', as that is the globe model used in FlightGear. | # Rightclick on the image in the layer sidebar and choose <tt>Set layer CRS</tt>, to select a projection model.

For example, the correct projection for Perth, Australia is <tt>Projected Coordinate Systems > Universal Transverse Mercator (UTM) > WSG84 / UTM zone 50N</tt>. Always select 'WGS84', as that is the globe model used in FlightGear. | ||
