Abstract
As new high-detailed imaging systems develop, new keys to interpretation must also be developed, especially when distance and perspective are changed dramatically. Low altitude, large-scale reconnaissance (LALSR) imagery is close enough to the ground to eliminate many of the traditional visual cues that exist in most aerial images. The perspective involved can be compared to looking at rust on wire bristles without seeing the whole brush. Now, individual species of plants are recorded, rather than general types of vegetation. Because of increased surface detail with LALSR, a publication covering image interpretation (II) keys would be too voluminous. For this reason, a user approach to the development of II keys for LALSR appears to be more useful and economical. The user, knowing his needs and environment, can best select and create those keys which apply. The selected keys will be based on the visual cues, perspective, and scales, peculiar to LALSR. Keys of this type can be enhanced by the system operator during flights because of his proximity in the target area. The potential of this system for on-site processing also assists the user in key definition. Example projects are outlined.
