基于GIS的地灾风险精细调查系统的设计与应用

Design and Application of Geological Disaster Risk DetailedSurvey System Based on GIS

通过分析地质灾害精细化调查的业务需求,采用移动GIS、WebGIS、内外业一体化管理、数据采集与存储等技术,构建地质灾害风险精细化调查系统,实现地质灾害风险调查室内资料准备、野外数据采集、室内资料整理3个环节无缝对接;移动端与浏览器端高效协同工作,统一调查手段、统一数据标准,极大地提高地质灾害风险数据采集、存储和查询的效率,系统已经在江西省调查项目中得到应用,缩短了调查周期和时间,实现了地质灾害调查的数字化、智慧化。

By analyzing the needs of geological disaster risk detailed survey,an field data acquisition and inert database system for geological disaster risk survey was constructed based on current technical requirements in geological disaster risk survey and combined with GIS related technologies.Mobile GIS,WebGIS,internal and external industry integration,offline data acquisition and storage were adopted to realize three practical and tightly connected functions in the workflow of geological disaster risk survey;integrating and processing of previous information before the survey,field data acquisition during the survey,and management of survey results after the survey.The mobile terminal and the browser work together efficiently to unify the investigation means and data standards,greatly improving the efficiency of geological disaster risk data collection,storage and query.The system has been applied in the investigation project,shortening the investigation cycle and time,and realizing the digitization and wisdom of geological disaster investigation.
