Abstract
A CAD-Based plane table surveying system is newly developed for topographic surveying. This system consists of a total station linked to a lap-top computer and the CAD software with survey programs. With the system surveyors elite figures and compile maps up to near finishes, while observing objects.
The system features:
1) high reliability of produced maps, because drawing figures and lines are monitored on a display at survey sites. 2) efficient survey works, because the system is provided with a resection program for free stationing and an intersection program for object point determination. 3) flexible data management because the system is integrated in a total digital mapping system controlled by a common CAD.
