摘　　要：我国目前采用多种坐标系,比较常用的坐标系如1980西安坐标系、CGCS2000国家大地坐标系以及城市地方坐标系,由于不同的部门采用的坐标系不完全一样,需要进行坐标系的转换,以满足相关部门的要求。本文以永安市1∶1000比例尺DOM产品为例,利用ArcGIS的Model Builder建模方法,实现CGCS2000国家坐标系批量转换到1980西安坐标系。China is currently used in a variety of coordinate systems,the common coordinate system such as the 1980 Xi′an coordinate system,CGCS2000 national geodetic coordinate system and the local coordinate system of the city,because of the different departments use the different coordinate systems,the need for conversion of the coordinate system to meet the requirements of the relevant departments.In this paper,taking the 1：1000 scale DOM in Yongan as an example,the Model Builder modeling method is used to realize the batch conversion of CGCS2000 national coordinate system to 1980 Xi′an coordinate system.
