基于GIS的水准路线分布图坐标修正系统

Coordinate Correction System of Leveling Line Map Based on GIS

  • 摘要: 针对纸质水准点高差表数字化过程中的坐标缺失及粗差问题,以基于GIS(方法纠正配准好)的水准路线分布图为参考底图,对不同粗差类型的高差表,综合利用水准点、水准测线的拓扑关系,相邻水准点的上下文关系,结合数据库技术,以图表交互的形式进行水准点坐标恢复、纠正等工作。结果显示:该软件可有效地修正缺失的水准点经纬度信息,数据精度满足要求,有效控制了坐标粗差产生。

     

    Abstract: Using geo-spatial relations of bench marks and lines, context relationship of adjacent bench marks, combining database technologie, based on registered line map using GIS method, we develop a software to solve the problem of gross error caused by the digitizing of paper bench marks. The results show that, this software can effectively recover the missing longitude and latitude information and data accuracy meet requirements, can effective control the coordinate gross error generation.
