The traditional aerial survey involves mounting a special gyroscopic, stabilized camera in the belly of an airplane and flying it at an elevation of between 15,000 feet and 30,000 feet, depending on the resolution of imagery you’re interested in. As the plane takes a predefined route over the desired area, it forms a series of parallel lines with about 40 percent overlap between lines and 60 percent overlap in the direction of flight. This overlap of images is what provides us with enough detail to remove distortions caused by the varying shape of the Earth’s surface.
When you click “Satellite” .. the data is not coming from a Satellite…. understand? It’s a bait and switch in your brain… like when you see a satellite dish on your neighbors roof.. it’s not going to a satellite.. it just picks up a signal.
