| Abstract: | This article introduces the structure and function of GNSS elevation fitting information and point environment visualization system based on Baidu map.The system is tested through the project case.The results show that the system can effectively judge the surrounding environment of point by selecting visual environment of point environment based on Baidu map,and select the point with better observation environment as the control point to construct the fitting model,GNSS high ground to achieve normal high conversion,improve the accuracy of GNSS elevation fitting. |
