Air observations using the rotor structure construction method and system for terrain data

The present invention obtains a high-resolution aerial image by cost-efficiently photographing the ground in the air and composing the terrain images. The present invention repetitively performs photographing by automatically dividing a determined area for photographing a specific area, dividing a photographing point corresponding to the optimal route and altitude, confirming the optimized image state in the air through automatic flight, and flying to a next photographing point.
