Abstract:In order to meet high requirement of orthophotoimages in special Karst landform, the authors chose Guohua rocky desertification monitoring area as the study area. DEM was built by OrthoEngine module of PCI based on 1:10 000 digitization contour map, and orthorectification of ALOS panchromatic image was rectified by RPC function model. Then, pan and multispectral data were merged with high fidelitily by PANSHARP fusion algorithm. Fusion orthophotoimages with spatial resolution of 2.5 m were completed after modification. This means can provide a referencre for high precision images and abundant information data for scientific research in Karst areas. In addition, it also provides a new scientific information updating way for Karst rock desertification monitoring.
