How to project remote sensing data on a surface determines the accuracy of the remote sensing data analysis results. The dramatically increasing large scope of high resolution remote sensing imagery requires an effective data structure. In recent years, a number of data structures for global geo-referenced data sets have been proposed based on regular, multiresolution partitions of polyhedron, named as geodesic Discrete Global Grids (DGGs). The DGGs can be used to manage global multi-resolution geospatial data effectively. Octahedral quaternary triangular mesh (O-QTM) is a common discrete global grid. An effective method for analysis of remote sensing data is proposed in this paper. The remote sensing data are transformed to image based on octahedral quaternary triangular mesh. Image overlay analysis is accomplished.
