J.W. Whitney J. A. Coe G. M. Fairer 1989 <p>Close-range photogrammetric techniques and newly available computerized plotting equipment were used to map exploratory trench walls that expose Quaternary faults in the vicinity of Yucca Mountain, Nevada. Small-scale structural, lithologic, and stratigraphic features can be rapidly mapped by the photogrammetric method. This method is more accurate and significantly more rapid than conventional trench-mapping methods, and the analytical plotter is capable of producing cartographic definition of high resolution when detailed trench maps are necessary.&nbsp;</p> application/pdf 10.2113/gseegeosci.xxvi.4.521 en Association of Engineering Geologists A close-range photogrammetric technique for mapping neotectonic features in trenches article
