用陆地卫星 TM 影象编绘黄土高原1:50万土地利用图

在研究目视解译卫星影象精度的基础上,总结了1:50万土地利用图遥感解译成图的方法和步骤,并以甘肃省景泰县为例,着重探讨了在卫星影象解译成图过程中制图综合的特点、判读标志与区域地理特征的关系等问题,就中、小比例尺地图的编制对传统成图方法和遥感解译成图方法进行了比较.

Compilation of 1:500 000 Land-use Maps on the Loess Plateau by Using Landset TM Images

According to the accuracy of visual interpretation,this paper deals with the method and steps of the compilation of 1:500 000 land-use maps using the way of visual interpretation of landset images,and taking Jingtai County of Gansu province for example and puts special stress on the character of cartogra- phic generalization and the relation between distinguishing mark of visual in- terprtation and the geographic character of area in the process of land use visual interpretation and mapping.Finally the paper compares the traditional mapping with the remote sensing image visual interpretation and mapping on the com- pilation of medium and small scale land-use maps.
