摘要:

电子地图是地理信息系统(GIS)的基础,在电子地图的制作过程中,为实现从地图的平面坐标到大地坐标再到屏幕坐标的转换,必须利用控制点的地理坐标.在实际操作过程中,控制点的地理坐标常用GPS(全球定位系统)测量获得.根据GPS在河南省公路电子地图制作中的使用情况,讨论了GPS控制点在矢量数据导出、坐标转换中的应用.并以孟津县和偃师市为例,说明了GPS控制点在地图数据转换、地图拼接中的作用.

Abstract:

Electronic map is the basis of geographic information system (GIS), in the process of electronic map production, in order to achieve the conversion from the plane coordinates of the map to the geodetic coordinates to the screen coordinates, it is necessary to use the geographical coordinates of the control point. In the actual operation process, the geographical coordinates of the control points are obtained by GPS (Global Positioning System) measurement. According to the use of GPS in the production of highway electronic maps in Henan Province, the application of GPS control points in vector data export and coordinate conversion was discussed. Taking Mengjin County and Yanshi City as examples, the role of GPS control points in map data conversion and map stitching is illustrated.
