Even current aerial photography, though, may present difficulties. Because of the great amount of detailed information they contain, conventional aerial photographs are commonly perceived to have considerable intelligence value. ~ a result, their distribution is sometimes controlled by military authorities and thus may not be available. H the project is large enough, acquisition of aerial photography may be a major activity and warrant special attention. A large number of private firms provide aerial photography services. Their names and addressses can be found in the telephone books of mrJor cities

Summary valuell then were calculated by multiplying the area of each Ipectral dau by the vegetation and lOil valuell derived from the lample tran.ect data for the entire .tudy area.
