Hi All! In february 2000, NASA flew a special shuttle mission to generate a near-global digital elevation model (DEM) of the Earth using radar interferometry. (see http://spatialnews.geocomm.com/features/srtm_jan2002/)
Amazingly enough, the complete results are freely available for download from ftp://edcsgs9.cr.usgs.gov/pub/data/srtm/ The data is segmented into one degree lat/lon chunks, with a planar resolution of about 30 m. The data are pretty raw, and should be treated with that knowledge, but hey, it's free! I only found out this the other day, and I have just downloaded data for Sweden. But I have not yet figured out how to put the data into MapInfo. I have looked at it with Global Mapper which works perfectly. Perhaps I can transform it from there. Another tip (from this list) is to use the 3dem software from http://www.visualizationsoftware.com/3dem.html which apparently can convert the .hgt files into something MapInfo understands. This remains to be tested. H�lsning/ Best regards Mats.E ________________________ FB Engineering AB S�dra F�rstadsgatan 26 211 43 Malm� OBS nya telefonnummer!

Does any one of you know from where I woul dbe able to get that.
