Methods, systems, and apparatus, including computer programs encoded on computer storage media, for unmanned aerial vehicle (UAV) flight planning. One of the methods includes receiving a location for an aerial survey to be conducted by a UAV. One or more images depicting the location are obtained, and a geofence boundary to limit flight of the UAV is determined. A survey area is determined, and a flight data package is created for transmission that includes information describing a flight plan. After the flight plan is conducted, flight log data and sensor data are received. The flight log data and sensor data are processed, and at least a portion of the processed sensor data is displayed.
