Spherical Discrete Grid System Thinking Geospatial Data Integration
Xi Zhang · Geomatics & Spatial Information Technology · 2013
With the development of the technology of earth observation,geography information and computer,geospatial data trend to multi-sources,real time and wealth. As a new digital earth reference model,discrete global grid system provides an uniform framework for the integration of geospatial data which is multi-resolution,multi-source and isomerism. The uniform framework that the discrete global hexagonal grid system provides for the integration of geospatial data are mainly discussed,with the method of the integration of geospatial data with multi-resolution,net resolution of data,and achieve dynamic management of magnanimity geospatial data.
