HI Not sure if this is of interest, but the is a 90m DEM available. Also, I am not sure, but I think that you can get it in the same file format as gtopo30, and so may be already readable by geotools2. Of course at 90m resolution, it is huge! PHilip Today JPL, NASA, NIMA, and USGS have released a 3 arc-sec (approx. 90 m) DEM of the South American continent. The data were acquired by the Shuttle Radar Topography Mission in 2000 and processed at the Jet Propulsion Laboratory. This data set joins the recently released North America DEM. Note that these are preliminary un-edited research-quality data products and are not intended for use in navigation or other critical, operations-related applications. Users should read the various documentation files available with the data. The data may be accessed at: ftp://edcsgs9.cr.usgs.gov/pub/data/srtm/ and will be available soon at the USGS Seamless Server: http://seamless.usgs.gov/ Additional information about SRTM data distribution may be found at: http://www.jpl.nasa.gov/srtm/cbanddataproducts.html NASA and NIMA welcome comments about the data as well as the results of any evaluations or analysis of these data. Please direct any comments or communications to Mike Kobrick at mko...@jp... or Tom Farr at tom...@jp.... |
