青岛市土地利用的卫星遥感数据计算机监督分类及面积量测

COMPUTER SUPERVISED CLASSIFICATION AND AREA MEASUREMENT BASED ON THE SATELLITE REMOTE SENSING DATA FOR LAND USE IN QINGDAO CITY

首先用陆地卫星５号的ＴＭ数据，进行青岛市土地利用类别的监督分类。将青岛市行政边界 数字化，作成数据文件。在计算机软件支持下，将行政边界画到分类图像上。将边界以外的像元 归零，统计边界内的像元数目，得到青岛市各土地利用类别的面积及总面积。

First of all, the supervised classification of land use was carried out Using the Landsat--5 data in Qingdao city. Then, the administrative boundaries of Qingdao city were digitized as a data file. Under the support of computer software, the administrative boundaries were drawn on the,classification map. The value of pixel beyond the boundaries was set to be zero, and the number of the pixed within the boundaries were counted. Finally, tile areas of various classifications and the total area were obtained.
