基于二元要素类映射池的空间数据转换技术研究

Research on Spatial Data Conversion Technology Based on Binary Factor Class Mapping Pool

数字化作业时代,工程勘察设计不仅需要在CAD格式的地图上进行建筑物的布置设计,还需要在GIS格式的地图上,利用便携移动设备中的GPS定位与地形图的实时关联功能,进行外业勘察数据的数字化采集工作。采用基于分层比对二元要素类映射池的技术方法,解决CAD与GIS空间数据格式便捷转换的问题,为工程勘察设计专业的数据共享提供解决方案。

In the era of digital operations,engineering geological investigation and design require the layout design of buildings on maps in CAD format.It is also necessary to use the real-time association function of GPS positioning and topographic maps of portable devices on maps in GIS format,to perform the digital collection of field surveying data.In this paper,mapping pool technology of the binary factor based on layered comparisons are adopte of,which enables convenient conversion between CAD and GIS spatial data formats,and provides a solution for data sharing in engineering geological investigation and design.
