辽宁省地表水资源遥感调查方法简介

Brief Introduction of Remote Sensing Investigation Methods of Surface Water in Liaoning Province

介绍了地表水资源遥感调查采用方法。用ER mapper图像处理软件、ARC/INFO和ARCVIEW地理信息系统 (GIS)软件 ,依据影像的形状、色调、纹理、位置、布局等建立各种地物解译标志 ,并对不同的解译对象选择不同的最佳波段组合和图像处理方法。解译、电子地图编辑、绘图全过程均在计算机上完成 ,大大提高了解译结果的精度和速度。

Some remote sensing investigation methods of surface wa ter are briefly int roduced. The software ER-mapper, ARC/INFO and ARCVIEW are used to establish i n terpretation symbols according to the shape, hue, texture, location and distribu tion of images. Different wave band combination and different image manipulation methods are used for different interpretation objects. The interpretation, comp iling and mapping of the electronic maps are accomplished on computers. This enh anced the precision and rapidity of interpretation.
