Hazard reconnaissance information system based on GIS

摘要

Geological hazard exploration and prevention in Three Gorges Reservoir Area is a great systematic cause, which is based on the data from lots of reconnaissance engineering projects in short time. The engineering projects are carried out by dozens of engineering groups from different industries like geology, mine, hydrology and so on. To keep the certainty and coherence of original data and productive documentation from these groups, GeoHazard based on Geographic Information System is designed and developed to meet the demands from the basic working units and departments of data management. Directed with the theory of the point-source information system, GeoHazard has a thematic database of point-sources as its core, and support the full professional operation of hazard reconnaissance from data acquisition, to map drawing, together with other basic functions on management. It is featured with the standardization of terminology, code and metadata, integrated management of all types of data and documents, and visualized data analysis, query and presentation.
