【摘要】 "5·12"汶川特大地震给北川县造成重大灾害损失,在开展震后地质灾害调查与评价项目的制图和建库过程中,存在大量的遥感图像、矢量与栅格图形数据以及属性数据需要采集、编辑、储存、入库、分析、查询和更新。本文以MAPGIS6.7为基础,在GPS与RS技术辅助支持下,系统地进行震后地质灾害空间数据和属性数据地采集、编辑、建库、分析和成果输出;并在此基础上总结了基于MAPGIS的震后地质灾害多源数据建库方法和实现技巧,从而实现地质灾害调查数据库规范化管理,满足了震后地质灾害区划评价、专题地图制作和灾后重建规划等对地质灾害信息的要求,为政府有关部门的灾后重建决策提供技术支持。更多还原

【Abstract】 "5·12 Wenchuan Earthquake"caused a major disasters loss in Beichuan County.In carrying out the mapping and the database construction of the post-earthquake investigation and evaluation of geological hazard,there are a large number of remote sensing images,vector and raster graphics and attribute data to be collected,edited,stored,warehoused,analyzed,queried and updated.In this paper,it systematically collects,edits,warehouses,analyzes and outputs the spatial and attribute data after the earthquake using MAPGIS6.7 and assisted by GPS and RS technology.On this basis,it summarizes the methods and the implementation techniques of the multi-source data construction database based on MAPGIS.It achieves the standardized management of geological hazards,meets the request of the geological hazards zoning,thematic map production and reconstruction planning and provides the technical support to the decision-making post-disaster reconstruction for the relevant government departments.更多还原
