oa Civil Engineering = Siviele Ingenieurswese - The application of aerial photography to engineering surveys

 

Abstract

A characteristic feature of the engineering type of survey is that the accuracy requirements vary widely between fine and coarse from survey to survey, depending on the purpose behind each survey. In cadastral surveying great accuracy of horizontal position is important to the exclusion of almost everything else, but in engineering surveys vertical accuracy is the more important in practically every case where aerial survey is applicable, that is in practically every stage of design up to the penultimate one. For this reason the stress is usually laid on a uniformly dependable accuracy of contours and faithful depiction of topography, and horizontal accuracy is usually a function of the allowable plotting errors.
