摘要
运用ArcGIS Desktop 9.0软件以海丰农场示意图为例,用DGPS进行控制点的测量,从建立坐标文件数据开始,把扫描的农场示意图(栅格图形数据)进行加载到地图中去并对其进行地理参考转换,使海丰农场示意图变成了一份具有地理坐标系统的数字化地图,从而为当前海丰农场精准农业研究提供了数字化的农场布局资料。
This paper used ArcGIS Desktop 9.0 software and took the sketch map of Haifeng Farm as an example to add a scanned raster dataset to a map and georeference it from measuring 4 reference points in Haifeng Farm with DGPS and establishing XY data table, At last a digital Haifeng Farm map with coordinate system was drawn from a man-made sketch map and it will provide fundamental digital map data of farmland distributions for precision agricultural research in Haifeng Farm.
