Some Key Techniques Research in Environmental Mapping Using High Spatial Resolution Remote Sensed Data

在大量实际工作的基础上 ,分别对影像的空间分辨率和像素分辨率的选择 ,色彩的匹配与还原处理等具体技术问题进行了总结与讨论。实践证明 ,这些处理方法在具体的应用中取得了很好的效果。

Recently,the environmental mapping is an important application of high spatial resolution remote sensing images.However,with the improvement of spatial resolution,the size and land cover details of imagery significantly increase.Those bring on some hurdles to image processing.In this paper,some key processing techniques are discussed including the choice of spatial and pixel resolution,color match and recovering.Actual works proves that these methods are very useful for environmental mapping based on high spatial resolution remote sensed images.
