摘　　要：目前,公路工程外业调查方式处于较为传统的状态.随着科学技术水平的发展,基于3D-GIS的外业调查系统将提高外业调查的信息化程度,外业调查方式将在以下方面发生重大改进:数据采集后自动与路线桩号关联,便于成果导出;设置在线协同办公功能,保证技术难题及时解决;实现构建三维地形,直观感知现场情况;定位中桩协助调查人员查找中桩,实时显示调查人员与路线距离;使用"标记点"功能,系统会在进入自定义的作业范围后,自动提醒该点位应注意的调查重点和难点.At present,the method of highway engineering field investigation is relatively traditional.With the development of science and technology,the field investigation system based on 3 D-GIS will improve the informatization degree of field investigation.The investigation method will be greatly improved in the following aspects:after data collection,it will be automatically associated with the path pile number to facilitate the export of results;online collaborative office function is set up to ensure timely solution of technical problems;3 D terrain with intuitive perception of the scene is constructed;the middle pile of path is located to assist investigators to work in the field;real-time display of the distance between investigators and the path is guaranteed;the"mark point"function is used;finally,the system will automatically remind workers of the key and difficult points that need to be paid attention to when they enter the customized operation range.
