目前,多光谱、高分辨率的SPOT5卫星遥感数据被广泛应用到森林资源调查中。本文采用GEOimage软件结合SPOT5卫星数据模型和一定比例尺的DEM,对SPOT5卫星数据进行正射纠正,利用PCI图像处理软件中的Pansharp融合算法合成影像,通过误差分析对比得出DOM符合精度要求并从色彩、纹理等方面增强了影像的可判读性。实践证明,这是一种适用于森林资源调查的SPOT5遥感数据处理的有效方法。
At present, multi-spectral and high-resolution SPOT5 satellite remote sensing data are widely used in forest resources survey. In this paper, GEOimage software combined with SPOT5 satellite data model and a certain scale of DEM ortho-rectification of the SPOT5 satellite data, the use of PCI image processing software Pansharp fusion algorithm to synthesize the image, the error analysis of the DOM complied with the accuracy requirements and from the color , Texture and other aspects of enhanced image readability. Practice has proved that this is an effective method for SPOT5 remote sensing data processing applicable to forest resources survey.
