SPOT5遥感影像在林业二类调查中的应用

Study on the Application of SPOT5 Remote Sensing Image in Forest Resource Inventory

采用ERDAS IMAGINE图像处理软件,对青海省互助县境内的北山林场的SPOT5遥感影像进行处理,包括原始数据导入、正射纠正、影像融合、波段组合、影像增强等处理过程以及数字正射影像图(DOM)的制作。探讨SPOT5遥感影像在林业二类调查中的应用处理方法及SPOT5影像的应用前景。经现地验证,以SPOT5遥感卫星影像为底图,通过人机交互目视解译方法区划判读小班能满足林业二类调查的需要,该影像数据能作为1∶10000专题图制作的基础数据。

Using ERDAS IMAGINE image management software,SPOT5 remote sensing image was processed for Beishan Forest Farm in Huzhu County,Qinhai Province,it included Raw Data Importing,Orthorecfification,Image Fusion,Band Combination,Image Enhancement processing process and Digital Orthophoto Map production.This paper discussed SPOT5 image in the application of Forest Resource Inventory,and the application prospect of SPOT5 image.By site verification,taking SPOT5 remote sensing satellite images as base maps,through man-machine interactive visual interpretation methods,this paper judged the small divisions could meet the needs of forestry II investigation,the image data could be used as the basis data for production of the matic maps with 1：10000.
