| 摘 要： | 采用遥感技术,以最新的遥感数据为基础,充分收集近年来新取得的地质资料和矿产信息,以多宝山地区为例,在森林沼泽景观区进行遥感蚀变异常提取研究。在遥感彩色合成影像上做掩模之后分别进行蚀变异常分级方法和蚀变异常信息提取,并参考地质图,依据不同区域影像中的色彩差异进行小区划分,再对各小区分别进行异常信息提取。这样不但减少了去除伪异常信息的工作量,而且使不同分级标准区分同一地区不同地物中成为可能,从而提高了异常信息提取的准确度。

| Abstract: | Taking Duobaoshan region for example, the research is on extraction of alteration anomalies of remote sensing information in forest and marsh landscape area on the base of data of remote sensing, by employing the latest technology and fully collecting geological data and mineral information that has been acquired in recent years.After masking of Remote sensing color composite images, alteration anomaly information has been extracted respectively with the reference of geological maps according to their different grades.In the color composite images, different research area is catalogued with different color.With data extracted from different research area, the removal of the abnormal fake information gets to be easy, and we make it possible to apply the distinct grading standard to the different types of land in same area and improve the accuracy of the anomalies extraction. |
