| Abstract: | Based on the forestry vector data of Yongping County,this paper used 91 satellite map assistant software and ArcGIS software to expound the methods of mutual transformation of WGS84,Beijing 54,Xi′an 80 and national 2000 coordinate system through the superposition of vector data of Beijing 54 coordinate system in each coordinate system,the calculation of transformation parameters and the transformation of vector data coordinate system,so as to realize the sharing of vector data of all kinds of natural resources. |
