Research on Optimized Spatial Data Query Algorithm in the Spatial Database

摘要：

Spatial objects are stored in the spatial database, which are expressed by spatial data and attribute data. Spatial data depicts the information about the location and shape of the spatial data, etc. Attribute data also expresses the non-spatial information about name and special attributes of the spatial object, etc. As the high volume of the spatial data and the complexity of spatial query and spatial objects, it is a hot topic of spatial database application to optimize the spatial query. This paper takes optimizing spatial data as study object, and optimizes the two handling processes of filtering and optimizing, and also study on all kinds of optimize algorithm.
