Automatic generation of ground surface information based on Microstation and LiDAR data

摘要

Traditionally, the ground surface information needed in highway location survey and construction drawing design relay on field survey, but this method is inefficient and has poor accuracy. In order to adapt to the complex environment of highway construction project and improve the efficiency and accuracy of the information, this paper presents a method for generating ground surface information automatically with light detection and ranging (LiDAR) data. A software for generating ground surface information automatically and accurately is designed on the secondary development based on the Microstation graphics platform. The software which integrates LiDAR, and highway construction design can improve the efficiency greatly and lower the cost in highway survey and design.
