矢量地形图数据建库的可行性办法研究——以南京市规划局建库为例

Study on the Feasibility of Spatial Database Building Using Vector Relief Map Data——The spatial database building in Nanjing planning bureau

以南京市规划局矢量地形图数据建库为例,详细地描述了矢量数据入库的处理过程。首先对入库的矢量图形数据要求做了概述,如要素的分层设色标准、地形图要素属性项定义等;然后讲述了矢量数据入库的流程和步骤;最后介绍了基础地理信息库的符号化处理。

According to the spatial database building in Nanjing planning bureau, this article describes the process of data loader for voctor data. Firstly, the request of vector map data is summarized, such as color-setting standard, attribute definition of topographic feature, etc. Then the data loader flow and process of vector data is presented. Finally, the symbolization of geographic information database is introduced.
