Seeking a solution, I found two new products that provide hope. In spring, before green-up covered the previous fall's rut sign, I used two mapping programs to explore the intricacies of the mountain: Maptech's Terrain Navigator Pro, a traditional topographic system combined with aerial photography, and Maptrails' GeoQuad, a similar product that links topographic maps with aerial photos. As a longtime customer of terraserver.com, I know the value of aerial photography. The problem with aerials, however, is that you can't alter them digitally. These programs have changed that.
