基于ArcGIS的地震活断层多源数据组织与管理研究
|
摘要
"中国地震活动断层探测技术系统"获取的全国20多个重点城市多源地震探测数据,旨在满足城市地震抗震设防的空间数据基础建设以及城市发展规划、土地利用、重大工程选址应用的迫切需求,分析不同来源的地震探测数据特征,建立中国活动断层探测与地震危险性评价数据库的概念模型。在此概念模型上,结合Arc-G IS的GeoDatabase模型给出了城市活动断层探测数据库具体逻辑模型,并按照地震系统确定的活动断层信息管理系统与基础数据库统一的建库标准和数据规范,实现多种活断层探测数据的统一整理和装载入库,完成了全国多个重点城市的活断层探测多源数据库建设,为"中国地震活动断层探测技术系统"各分工程的实施提供了数据保障和数据服务。
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.
