[gdal-dev] Unexpected behavior on gdal2tiles.py

[jratike80]

Hi,

Tiles created by gdal2tiles are never georeferenced directly but only
through the tileset definition. I had a try with your coordinate system with
raster profile and by looking at the generated tilemapresource.xml it seems
to me that the tileset is correct and tiles georeferenced right. Client that
reads the tilemaprerource.xml or that is configured manually to use the same
tileset should show correct coordinate, including a knowledge that the tiles
are from Mars.
