Terraform should do either of these but my time is limited so I haven't been able to check it - try your luck!! http://prdownloads.sourceforge.net/terraform/terraform-0.9.0.tar.gz?use_mirror=unc About terraform: http://terraform.sourceforge.net/index.html also might have something here http://www.tnris.state.tx.us/gistools/mapviewers.htm I'm sure MicroDem will do xyz's but the program is a little confusing if you're not used to dealing with this stuff. I have another thread in here somewhere about using MicroDem for lasooing areas of the world etc. Some other useful links are in there. After installng MicroDem hit the In-Out button on top and then hit the import button in the data manipulation bar - you'll get it after that. Good luck! Bot
