A Study on Organizing and Managing Multi-source Seismic Active Fault Data Based on ArcGIS
基于ArcGIS的地震活断层多源数据组织与管理研究

In order to meet the urgent need of building spatial data infrastructure for urban anti-earthquake defense,and to make decisions for urban developing planning,landuse planning and site analysis of major projects,this paper firstly applies a feature analysis on multi-source seismic data based on seismic probing data acquired from "National Seismic Active Fault Probing Technique System" program to depict data's major characteristics;secondly,a concept model is built respectively for active fault probing database and seismic risk assessment database;thirdly,considering the requirement of storing and managing original geo-physical,geo-chemical and geological survey data and associated log files,which may be attributes of spatial data in enterprise database as well as spatial data,a set of BLOB based archive tables and archive records to feature linkage principle are designed and developed;and then this concept database model is implemented using ArcGIS Geodatabase specification and UML tools;finally,we design and implement a series of work flow and conversion tool to import,transfer and re-construct probing source data into database schema.
