Hi Jason, Maybe Jon has hit the point - try 3 instead of 1 ;=)) thanks, Jon... And I think the 'new' location of the data is :- NASA_WGET="ftp://e0srp01u.ecs.nasa.gov/srtm/version2/SRTM3/Australia"; But I have found a MISSING DEM block. I tried to do Sydney, but found no S40E150 on the above FTP site I found - OZSET="S31E150 S31E151 S31E152 S31E153 S32E150 S32E151 \ S32E152 S32E153 S32E159 S33E150 S33E151 S33E152 S34E150 \ S34E151 S35E150 S35E151 S36E150 S37E150 S38E150" But could not find data for say S40E150??? My only alternative was to switch to using GLOBE data... Cut from my makesyd script... # (b) Try USGS DEM files USEUSGS=1 # DEM data # source = http://edcwww.cr.usgs.gov/products/elevation/gtopo30/gtopo30.html USGS_URL="http://edcftp.cr.usgs.gov/pub/data/gtopo30/global/"; USGS_MIRROR="http://www1.gsi.go.jp/geowww/globalmap-gsi/gtopo30/data/global/"; # OZ_USGS="http://edcftp.cr.usgs.gov/pub/data/gtopo30/global/e140s10.tar.gz"; If you find any other (free) DEM/SRTM data for OZ, I would be most interested... Regards, Geoff. PS: You can get my full makesyd script from :- http://geoffair.net/tmp/makesyd but it requires you have VMAP0 in a specific directory, but maybe you are not using VMAP0... and be aware it FAILS.
