基于GIS和RDB的勘察数据一体化管理

工程勘察中的原始数据、成果资料中包含着较强的关联关系，有效地利用和表现这些内在关系有利于数据的存储管理和检索使用，因此勘察信息系统不仅要实现数据采集、图件编绘等的计算机辅助化，更要在成果使用管理上发挥计算机技术的优势，以体现勘察成果间的内在联系。在分析及明确了各类资料间固有的联系基础上，建立了基于GIS（地理信息系统）的数据模型和资料生成模式以及基于RDB（关系数据库）技术的勘察资料管理模式。结果证明，基于GIS和RDB的勘察信息系统不仅可以满足基层单位用户的业务需求，而且可以可自动建立成果间的联系，实现勘察数据的一体化管理。

Integrative management of survey data based on GIS and RDB

There are apparent spatial connections between the raw data and drawings of the reconnaissance survey, which may be useful to store, manage, query and deal with these data and drawings. For this reason, computer-technology-based survey information system should play a great role in not only the data acquisition, map drawing, but also in the data management of documents, multimedia, maps and other digital data, according to the inherent relation between them. This article gives illustration of the relations and sets up a practical model on the maps drawing, storing and management base on GIS (geographical information system) and RDB (relational database). The application examples in the Three Gorge reservoir are shown; and it is proved that the model can meet demands of both the operation survey entities and the management departments.
