摘要
利用 1998年 9月 2 8日 TM卫星数据 ,经过数据校正、影像增强和非监督分类等处理 ,制作卫星影像分类图 ,建立判读标志 ;利用全球定位系统 (GPS) ,结合地理信息数据进行实况调查 ,建立卫星影像分类解释依据 ,标定土地利用类型 ;借助 Arc/ Info GIS、Arcview GIS划分流域土地利用类型。
Landsat/TM image data was used as data source in the study, and the image data was processed with the support of the methods-geometric correction, spatial enhancement and unsupervised classification. And using global positioning system (GPS), with some geographic information data, we have had filed survey to demarcate the classification image. Then with the assistance of Arc/Info geographic information system (GIS) and Arcview GIS, a vector graph was made, and a classified map of land use types was output.
