FSX ASTER_imp GDEMv2 30m mesh for South Korea (ROK)
43.88Mb (662 downloads)
"imp" means imperfect, as other mesh I have already processed is of areas that have very little vegetation cover - over the land, or has large urban areas. This "imp" mesh will include some slight discrepancies of altitude (in the case of forested areas - by a magnitude sometimes of +15 metres-depending on how tall the trees are, in the jungle or forest canopy) over urban areas, or areas with a lot of vegetation cover - due to the limitations of the ASTER satellites infra red scanning cameras, and the software used to process the DEM data. Areas where there is little vegetation cover, or non urban areas, the terrain should have truer values. But I feel this ASTER DEM data is so good - why let it all go to waste - especially flying over lovely Pacific islands? So you FSX users out there will have to take all this into account when using this mesh. Grateful thanks to ERSDAC, and NASA for making this data freely available to the public.

ASTER GDEMv2 30m mesh for Galapagos Islands
3.58Mb (632 downloads)
ASTER GDEM Version 2 is a 30 metre definition DEM, its better than the version 1 data that ERSDAC, of Japan and NASA originally released, but it does have its limitations. GDEM has been obtained from a satellite that uses stereoscopic infrared scanning cameras, this brings with it problems in the resultant data.....where it sees the tops of trees, buildings etc, as the ground terrain. If you look at the jpg image with the terrain type errors shown as a graph, you will see that the only 'safe' terrain to use this data with - in FSX - is scrubland, or desert terrain. Its hopeless in defining the terrain in places like Europe - with all the artificial structures, (buildings) and different types of woodland, so any mesh I create from this data won't include areas like that....it will be more desert type terrain, and scrubland. I won't be doing Greenland because something about the ice around Greenland, (or any other land mass with ice) it creates false data. It does give enough fine data to reveal railway lines, and some roads though. This mesh has been made for FSX only.
