formation, however, would undoubtedly be more easily classified if 
at least some of their spectral characteristics were known along with 
their size and shape. The often heard argument that a well-trained 
botanist, soil scientist, geologist can obtain all the information 
required from panchromatic, 1:20,000 scale photography may be true, 
À but these qualities are formed from years of training and experience 
and with the demand placed on remote sensor technology today, training 
has to become more efficient. 
arr Multispectral aerial photography can provide the following 
oF benefits and capabilities for interpreter training: 
f 1. More cost effective for imagery acquisition than multicamera 
or multi-overflights with a single camera. 
2. Environmental and equipment factors are held constant during 
acquisition. 
3. Utilization of the electromagnetic spectrum from approximately 
350 to 900 micrometers. 
e 4. Increases the confidence of interpreter decisions by providing 
for more than one type of photo of the same area.
