Abstract: A low‐cost, digital, three‐dimensional photogrammetric mapping system has been successfully developed and implemented on a microCAD system. Code‐named PMCAD, the system allows both two‐dimensional line maps and three‐dimensional ...

Abstract: The manager of a professional surveying practice is often confronted with the seemingly simple, but actually rather complicated, task of assigning surveying projects to different survey parties at different times. His or ...

Abstract: The steady decrease in cost of a digital camera and frame grabber, together with higher resolution will result in more photogrammetric applications using such a camera. This is because of the advantages of speed and ...

Abstract: This paper describes the design and development of an efficient, inexpensive, and fully automated method of generating accurate off‐line digital charts from microcomputers. The method involves the integration of existing ...

Abstract: Electronic total stations and data collectors have come to be recognized as vital productivity tools in the age of digital mapping. Information encoded in data collectors represents the first and, perhaps, most important ...
