利用GIS技术综合多源地学空间信息,应用于区域地质调查的重要方面——野外空间数据采集。根据我国1∶5万区调工作流程和数据采集的特点,在野外空间数据采集子系统中应用系统工程的思想,采用MapGis和ArcView工具型地理信息系统软件,进行二次开发;从野外空间数据采集的标准化、数据字典、地质观察点定位、空间数据及其相关的属性数据的一体化采集、素描图的绘制等方面加以研制,初步实现了1∶5万区调系统中的野外空间数据的可视化快速采集技术,并成功地应用于试点区。

The advantage of GIS technology in combining multi-sources geoscience information is used in the important aspect of regional geological survey-field spatial data collection. With reference to the process of 1:50,000 regional geological survey in China and its data collection characteristics and with adoption of system engineering in“Field Spatial Data Collection Sub-System”, MapGis and ArcView which are the tool-type geological information system software are applied and re-developed. The authors research the following aspects of field data collection: standardization, data dictionary, positioning of geological observation point, integrated collection of attribute and spatial data, sketch drawing, and initially realize the visualized rapid collection of 1:50,000 regional field data, which has been successfully applied in experimental area.
