Anyways is alway advisable not to wear the glasses for a long time and without breaks.I never used the anaglifo glasses,but with the active ones i had somes headashes, unless in the first week ,if you have a lot of images to analyze maybe you need to search a little help

Hi, maybe cutting the areas with forest to the SRTMs and make them a subtraction between an estimative height value of the trees and the z value of each cell, and finally putting them together again...

Hi, I have a bit of experience been working with the Purview extention for Arcgis,it have a total compatibility within arcgis 9x at least,i'm not sure if it can work with Arcgis 10.
