I have developed an airborne mapping system using unmodified digital SLR cameras that creates digital elevation models and orthorectified image mosaics that can be used to map anything from glaciers to caribou to truck tires with these specs:
Other systems have been around for a while that can also do this, or something close to it. What’s different about mine is that it is affordable enough to make time-series of these maps, opening up brand new lines of scientific inquiry.
