摘要
论述了草地 GPS测量 ,GIS成图的简易方法 ,用于绘制中等比例尺实验样地的电子地图 ,计算地块的面积和测量点间的距离 ,分析面积和距离的测量误差分别介于 0 .3%~ 3.0 %和 0 .15 %~ 1.5 0 %之间 ,表明这一方法适用于草地的简易测图 ,优于草地测图的传统方法。
A simple method of cartography in grassland using GPS and GIS was discribed. Grassland electronic map could be drawn, the area of regions and the distance of two random measured points could be measured using this method. The error of area measured was between 0.3%~3% and the error of distance measured was between 0.15%~1.5%. It is concluded that the method can be used in cartography in grassland, and is superior to the traditional methods.
