All aerial photography is conducted by observers. Still aerial images are normally high definition in either JPEG or RAW format. Images may be transmitted directly to the ground and are normally geo-referenced. Image files can be passed to user agencies after landing by internet links or directly on memory sticks.
Agencies may require hundreds of images in the form of wildlife, geographical, archaeological, pollution, storm damage or other type of survey. A pre-flight meeting with the agency is normally necessary to discuss exact survey requirements. Aerial photographs are normally provided with overlap, GPS tagged and taken in the best conditions and at the very highest resolution.
