I am attending the inaugural Commercial UAV Expo in Las Vegas this week. It is very, very interesting… to see this burdening new industry. The potential is tremendous for the surveying, mapping and GIS industry. It is very interesting to see the mix of people and professions attending. For me the big news is not the flying little machines but more the software applications that create GIS data. We can fly huge areas and convert digital images into very accurate topography. There are many applications.
