The fly ends on the Mt Blanc, in the Chamonix valley.

srtm4 is a height field. there is a special value for sea level, but
that's all. From what I understand of the problem with current scenery,
it is less a data problem than a bug in the triangulator. Having worked
on fgsd for several years, I know that these issues are tough to tackle.

The algorithm I am trying to implement doesn't use triangle to define
landuse. Instead, the earth surface is divided into squares of different
size ( there are currently 16 lod, there will be 20 with srtm ), and each
square has its own texture. The mesh is a regular, square mesh made with
triangle strip.
