| Abstract: | The measuring and recording method (MRM) with memory of electronic tachometer and draft is one of the main fieldwork models of large-scale digital mapping by EPSW(Electronic Plane-table Surveying and Mapping System for Windows)software. The error of detail survey would happen because of mistakes of zeroise or the wrong place of back-sight. This paper puts forward a simple method for correcting these mistakes by setting up a virtual back-sight target without programming. |
