METHODS AND APPARATUS FOR ACCESSING GEOSPATIAL INFORMATION

摘要

Methods and apparatus are provided for accessing geospatial information. A geospatial toolkit (111) including source, handler, and data modules is configured to access geospatial data from a variety of sources (101), parse the geospatial data, and provide geospatial data in a unified format. Parameters including source, layer information, boundaries, query filters, etc. are set to allow retrieval of diverse geospatial data from different sources while providing a unified presentation on a system interface. The geospatial toolkit can be implemented in a framework such as the Component Object Module (COM) or NET framework (131).
