基于信息映射技术的DWG地形数据入库方法

Storage Method of DWG Terrain Data Based on Information Mapping Technology

随着测绘与地理信息产业的蓬勃发展,许多绘图软件应运而生,也因此产生了多种多样的专用数据格式,当需要建设数字化地形图数据库时,多源异构数据必须转换成统一格式的入库数据。本文基于EPS平台的信息映射技术,提出一套可行的DWG地形数据整理入库方法,并运用此方法对珠海约365 km^(2)的1∶500地形图进行了数据入库,取得了良好效果。

With the rapid development of Surveying and mapping and geographic information industries,many mapping software emerge as the times require,and a variety of special data formats are produced.When it is necessary to build a digital topographic map database,multi-source heterogeneous data must be converted into a unified format of storage data.Based on the information mapping technology of EPS platform,this paper puts forward a set of feasible methods for the storage of DWG topographic data,and the method has been applied to the data storage of 1∶500 topographic map of about 365 km^(2) in Zhuhai with a good result.
