基于TM图像的矿区土地资源分类提取研究

he land resources classification and extractions on TM images are the first tache to establish the dynamic monitoring of mining area. Use TM image as data source to build Shenyang mining area land resources classification system, and use the sub area stratiform method to classify. On this basis, through the spectral analysis of TM images, research the classified extraction model of mining land information. With the help of GIS spatial analysis, extract the changed information among the mine land classification, which will provides the data preparation for the future dynamic monitoring analysis of mining area land resources.
