Abstract

Abstract

Space-based design features eological data warehouse, unlike the traditional warehouse based on time. The key concept in the design of the multi-dimension model is to choose suitable multi-dimensions, such as spatial, temporal and attribute dimensions, and determine the granularity and measure, according the data requirements of the subject involved. A geohazards data warehouse of the Three Gorges Reservoir Area is built on 5 subjects to integrate the mass data in different space and time scales; the experiments show that the warehouse makes the geohazards prediction more accurate and rapid in two ways: Firstly, it enables fast search of the data since the data are re-organized by geohazards type, alarm levels and data layers; Secondly, it facilitates the discovery of the geohazards laws from data warehouse through the data mining tools.
