Author: Bernstein, David A.;

Date: 1961

Source: PNW Old Series Research Note No. 212, p. 1-5

Description: Aerial photo stereograms are valuable for showing neophyte photo interpreters the stereoscopic appearance of common objects and conditions. They are also useful for instruction in measuring heights, horizontal distances, and angles on photos. Collections of stereograms of known conditions are worthwhile reference material for interpretation work in unknown areas.
