摘要
借助地理信息系统技术,分析、明确了各成果资料间固有的联系,建立了基于GIS和RDB技术的勘察资料生成、存储、管理使用模式,并以Geoview为GIS平台开发了地质灾害勘察信息系统———GeoHazard,该系统不仅实现了当前基于CAD的勘察系统的可视化数据采集存储、图件编绘功能,而且实现了地质灾害勘察过程中的文档、图件、属性记录等的一体化关联存储。
The existing CAD-based survey information systems are not so good in data security and document index because of the deficiency of relationship between spatial data（or drawings） and attribute data （or documents）. While GIS technology is available to replace it for this purpose. This article illustrates the relations and sets up a practical model on the maps drawing,storig and management based on GIS and RDB. Also an example of GeoHazard is given,which,based on the GIS software of Geoview, could play a great role not only in the data capture, maps drawing,but also in the data management of documents,multimedia,maps and other digital data,according to the inherent relation between them.
