基于Omap的信息化公路工程地质调绘

Information highway engineering geological mapping based on Omap

随着平板电脑、智能手机普及及地图查看APP功能的增强,公路工程地质调绘已由携带纸质资料、罗盘、地形图定位的传统工作方式转变为集地形、地质、设计资料于一个平板(手机)地图查看APP内的信息化调绘方式。在信息化调绘过程中收集的基础资料导入及现场记录信息的导出是关键,以Omap APP为例,给出无坐标属性的区域地质资料位图文件制作成自定义地图;具有坐标属性的地形、不良地质、建筑物、勘探布置制作成.kml文件;APP记录数据导出至CAD,GIS软件的过程及方法。经国内外多个高速公路、水电站项目使用,实践证明行之有效。

With the popularity of tablet computer,smart phone and the enhancement of map viewing APP function,highway engineering geological mapping has changed from the traditional working mode of carrying paper data and positioning by compass and topographic map to the information-based mapping mode of integrating topographic,geological and design data into a tablet(mobile phone)map viewing APP.The import of basic data collected and the export of field record information are the key in the process of information-based mapping.Taking Omap APP as example,this paper gives the regional geological data bitmap file without coordinate attribute to make a user-defined map,the terrain,poor geology,buildings and exploration layout with coordinate attribute to make a.kml file,and the APP record data to export to process and method of GIS and CAD software.It has been used in many highway and hydropower projects at home and abroad,and has been proved to be effective.
