Description
Summary:Massive volumes of global geospatial information are being collected by newly designed acquisition devices and generated by various geospatial applications. This poses a critical challenge to efficiently organize and effectively integrate global multi-source geospatial information. This paper introduces a global seamless data model for the organization of huge multi-source, multi-resolution and multi-temporal geospatial data. Based on this data model, the management of the global multi-resolution pyramid is discussed in detail. To integrate geospatial data and processing functions from various GIS systems, a service-oriented framework is presented through the technology of Virtual Globe. Finally, a Virtual Globe system, GeoGlobe, is developed and illustrated.
