| 摘 要： | 统计分析了湖北保康磷矿区有关目标地物(道路、建筑物、坡耕地、植被、水体及阴影等)的SPOT 5影像特征,认为它们具有一定相似性和差异性,依赖单一的遥感分类方法难以实现对矿区开采面及固体废弃物信息的准确提取.采用决策树分类方法,设置一定的分类规则,结合数字高程模型和含矿地层等相关辅助数据,逐一对矿区相关地物进行分类,经分类结果后处理,分类精度达83.4%.

| Abstract: | Based on a statistic analysis of spectral characteristics of such objectives as road,building,sloping farmland,vegetation,water and shade on the SPOT 5 remote sensing image in the Baokang phosphorite ore district of Hubei Province,this paper holds that spectral properties of these objectives have certain similarity and difference,and it is difficult to extract the mining area and the solid waste accurately based only on a single classification method.Making use of the decision tree classification and settin... |
