Abstract

In order to improve the efficiency of measurement, total station data extraction and transmission system based on AutoCAD is designed and implemented by the secondary development of AutoCAD software in the paper. The system is composed by communication module, data conversion module, point-plotting module. The system connects with the total station and collects automatically data to extract useful data form initial data, then automatically calculates and stores the coordinates, taking Visual Basic.NET as the development platform to realize AutoCAD-based plotting and mapping. Test results show the system realizes the integration of internal and field operation and can reduce the workload of manual editing and error rate, so as to improve the efficiency of internal operation for measurement.
