Hi
I'm trying to get data from the USGS Seamless Data Distribution into Dreamscape. I can download a GeoTiff file and then output DEM via the 3DEM freeware programme. The trouble is, when I import as a terrain, I get several spikes where pixels must have enormous values. Another problem is that the map appears to be right/left flipped.
I realise these probably aren't Dreamscape problems, but can anybody suggest how to fix them? I've tried going via Terragen, but the data values seem to change and I lose accurate sea level.
thanks
