Research and realization on integrated management of multisource heterogeneous satellite data based on spatial database

摘要

Based on spatial object and relation model of spatial database management system, this paper propose an “integrated spatial data-attribute data” standardized data structure of multisource heterogeneous satellite data. The structure is described by spatial table, and provides a unified access and processing interface of multisource heterogeneous satellite data. Using this standardized data structure, we can provide protection for satellite data management application system of "Single-requirement and multi-satellite".
