Abstract

With the enrichment of earth observing measures, the interesting field of photogrammetry and remote sensing monitoring has expanded gradually to the whole world, traditional planar data structure no longer satisfies the globaloriented application of geo-spatial data. Breaking through the constraints of planes, managing and utilizing remote sensing spatial data in the real earth mode have now become an inevitable trend. Discrete Global Grid System (DGGS) provides new ideas for the constructing of new spatial data models. Based on the frame of DGGS, this paper designs a new hexagonal hierarchical structure of remote sensing data that has the attribute of geographical location. Compared with the traditional image rectangular quadtree structure, this structure is more applicable to the management and arrangement of global spatial data (especially the raster data) and can express and process multi-resolution global geospatial data seamlessly.
