I got my new Garmin GPS three days ago. Completely useless in Bankok, but as I'm currently working on an irrigation system, I decided to use it to do a land survey. It seems to be working fine beside the altitude that doesn't seem really reliable.
Now I'm trying to generate a map based on all the data I collected but so far I've been unable to find the right software. First I downloaded terraplot (www.terraplot.com) but it doesn't work (!??). Then I tried COPAN. The problem is I need to download a key from www.underhill.ca/Software/ugl_software.php but I'm unable to access this site.
Does anybody has any idea where I can download a software that can make good use of all the data I collected this morning ?
