摘要
数字地质填图是指区域地质调查数据的野外获取及其成果的数字化统一性再现 .当前数字地质填图现状和发展趋势已基本上实现了数字填图系统的采集、存储、管理、描述、分析和再现地质实体在地球表面空间分布有关的数据信息 .在计算机辅助下 ,通过野外观测路线的调查 ,对地质、地理、地球物理、地球化学和遥感等多源地学数据进行综合分析和地质制图 .在掌上机WindowsCE平台上 ,实现了数字填图所需的基本GIS基本功能 (GPS定位路线采集、素描 ) ,实现了遥感系统与数字填图系统的一体化整合 .
Digital geological mapping obtains regional geological survey data in the field and re-shows its production in digital regularity. At present, achievements have been made in the data collecting, storage, managing, describing, analyzing and reconstructing of the geological body information with space distribution in digital mapping system. With the assistance of computer, we can synthetically analyze multi-source geological data of geology, geography, geophysics, geochemistry and remote sensing from field geological observations. We have also achieved basic GIS function (GPS orientation, routing collection, sketch) under the Windows CE platform in the laptop computer and attained the conformity between remote-sensing and digital mapping system.
