----------------------------Original message---------------------------- Hi, Folks, I'm a biology grad student in U of alaska Fairbanks, facing a challenge for which I believe some of you have a good solution. What I'm trying to do is layering 2 graphic files, habitat map and the home range boundary of my study animals. Habitat maps are traced from USGS maps and aerial photos with Zoom Transfer Scope. I have an access to a scanner. The home range boundary files are strings of UTM coordinates, can be written in either ASCII or binary format by a program called CALHOME. Yes, I can enter UTM points to the habitat map manually one by one, but the boundaries are curved lines like topographic contour lines, consists of several hundreds of points for each line. It would take awful lots of time to do it and the accuracy of results are questionable. I could bother you with further detail but I stop here. Any suggestions and/or infos about programs which can do the job are appreciated. My e-mail address is: [log in to unmask] Thanks for your time and space.
