Photogrammetric Recording of Historic Transportation Sites

摘要

The purpose of this study was to evaluate the applicability and accuracy of documentation drawings prepared from close-range terrestrial photogrammetry and to compare them with the results of traditional documentation techniques which depend on hand measurements. The photogrammetry research was organized to coincide with equipment resources available within the Virginia Department of Highways and Transportation. The sites studied on a case-by-case basis illustrate the types associated with transportation improvements that are likely to be affected by federal requirements which demand documentation of certain historically significant sites. The variety of sites also demonstrates the adaptability and limitations of the photogrammetric method. Documentation drawings executed by the photogrammetric method are presented in several stages of completion to illustrate the process.
