Spatial Data Access Based on Data Registration Center and World Wind
摘要
Abstract
Traditional centralized databases and file systems cannot effectively handle the massive growth in data access and man -agement, and are needed to adopt a distributed storage .Meanwhile , along with the rapid development of spatial information , GIS applications gradually come into people’ s lives.For spatial data access , this paper combines the data registration center with World Wind Java to achieve the spatial data access .First, by using the separately distributed storage way of metadata and data , KML is taken to organize and manage variety of spatial data attributes to realize the spatial data storage ,and finally , World Wind Java is used to implement the read and display of spatial data , in order to effectively access the collected spatial data ,provide services for applications , give full play to the role of data , and greatly reduce the burden of spatial data storage .关键词
