矿产违法开采信息的快速提取

Rapid Extraction of Lawless Mining Information

采用HIS彩色变换并利用遥感数据提取矿区变化区域,将变化区域与土地利用现状矢量数据和采矿权登记矢量数据相叠加,利用地理信息系统快速提取叠加分析功能剔除干扰区域,实现违法采矿信息的自动提取。该方法充分利用遥感数据和矢量数据,避免了单独使用遥感影像数据时必须进行人工监督分类的繁琐操作,其提取违法信息的速度快、费用低廉,有利于及时发现并制止矿产违法开采行为。

This paper uses the method of HIS color transformation and remote sensing image data to gain mining change regions. It overlays changed region on land using data and mining register data, finds and removes the disturbing regions by using GIS analysis functions. The system can attain the illegal information automatically. This method takes full advantage of image data and vector data to avoid employing supervised classification when using the image data only, which is manual and fussy. The method can be used to extract the illegal information rapidly, at low cost and is useful for stopping lawless exploit minerals in time. The method can be mastered easily even the man has no professional technology.
