I'm wondering if someone with a bit more experience can help me here. I tried using some dems from here:
http://edcftp.cr.usgs.gov/pub/data/DEM/250/A/
and after I gave them a .dem file extension there was no problem getting them into Vue.

I have some Australian dem files with an .xyz and .grd file extensions and I can't get them to import into Vue. (Just changing the ext. doesn't work.) Like the files from the above link they are an ascii format clearly indicating point positions in 3d.

Can anyone offer some helpful info for converting them to a useful format?

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

PS MicroDem is linked in the 3rd link I gave you above! bot

Thanks for the info. I've also found that Accutrans will load the grd files and then export them in various formats. http://www.micromouse.ca/

Yeah, thats a good one too, lots of formats supported If you're into it you might want to check out 3dem also for these kind of projects. Both 3dem and MicroDem are good for merging dems and other data sets if you want to cover large areas. I've had Accutrans seize up before on larger projects. bot
