桂林市地面岩溶塌陷预测图件编制

探讨了采用ＧＩＳ技术编制系列图件的方法、过程及特点，即运用ＭＡＰＧＩＳ地理信息系统平台，通过扫描原图并进行栅格图纸纠正，然后矢量化转换成矢量数据，进行线型、颜色、线宽等编辑；分别按专题要素层、地理要素层、整饰图层分层入库；根据专题需要组合成工程文件从而生成各专题数字图件。该方法成本低、成图周期短且便于相关专题地理信息系统的建立和开发应用，并为研究桂木市地面岩溶塌陷和进行桂林市岩溶塌陷预测及防治提供

ESTABLISHMENT OF GROUND DISSOLVED ROCK CAVE IN FORECASTING MAP OF GUILIN

According to the study of ground dissolved rock cave in forecasting and prevention and cure, discussing the method, process and it's characteristic of establishing series map by using GIS technology has been made. Namely, MAPGIS is applied to scanning source maps, correcting grid drawing, then changing to vector date; editing, delaminated saving, and then getting need map. The method has the characteristics of lower costing, high efficiency, easy to build the geography information system of corrective special topic. It also can provide the base date for studying ground cave in giving forecast, prevention and cure of Guilin.
