Some field observations on OSI aerial photography scales
The US, UK and USSR are attempting to negotiate a Comprehensive Test Ban Treaty (CTBT) in Geneva. One of the verification procedures presently proposed provides for the possibility of conducting an On-Site Inspection (OSI) if a violation is suspected. According to the terms of the draft treaty, the OSI team would be provided with either (1) stereoscopic aerial photographs with a scale of 1:2,500, or equivalent topographic maps (US version) or (2) a large scale aerial photograph (USSR version). In order to gain a better understanding of the aerial photograph issue, EG and G was asked to take stereoscopic aerial photographs of two areas at the NTS at four different scales, 1:2,500, 1:5,000, 1:10,000 and 1:25,000. The purpose of this paper is to present some field observations on the use for OSI type purposes of these different scale photos.
