Flight Altitude

The altitude of your flight will depend on the type of aircraft you select, and the sensor quality it possesses. In general, for us to be able to deliver CAD drawings that meet surveying accuracy standards of 0.1 ft, we recommend a flight altitude of 150 ft along with a 20-megapixel camera resolution and 0.5-inch ground sampling distance (GSD).  

That being said, your flight altitude can be higher or lower depending on the accuracy requirements of your specific project.  Accuracy is also dependent on the number and distribution of ground control points, the control collection methods, and processing techniques.
