Design and Application of Geological Disaster Risk Detailed Survey System Based on GIS
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 geo-logical 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 impro-ving 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 geolog-ical disaster investigation.
