摘　　要：结合已有测绘案例,基于ArcGIS平台,通过"创建自定义地理(坐标)变换"与"投影变换"两个步骤自定义测区中央子午线与七参数,完成了原始GPS观测数据从WGS84大地坐标向CGCS2000国家大地坐标的严格转换,得到了良好效果,满足了工程需求。在工作效率上,该方法较以往传统转换方法有了显著提高,值得应用与推广。In this paper,combining with the existing mapping case,based on the ArcGIS platform,we used the two steps of creating custom geographic(coordinate)transformation and projection transformation,to customize the central meridian and the seven parameters.This method can realize the strict transformation of the original GPS observation data from WGS84 geodetic coordinate to CGCS2000 Gauss plane coordinate,have good results and meet the needs of the project.The efficiency of this method has been significantly improved compared with the traditional conversion process,which is worthy of application and promotion.
