Design and Implementation of Disaster Risk Spatial Data Collection and Updating System Based on Mobile GIS
In the comprehensive risk survey of natural disasters and subsequent daily management work,a large amount of on-site sur-vey,field data collection,and indoor data uploading and updating work are required. In order to scientifically and reasonably schedule field investigation tasks and improve field work efficiency,this article establishes a disaster risk spatial data collection and updating system based on mobile GIS. It realizes the integrated management method of the entire process of mobile positioning and collection,offline storage,format conversion,result uploading and updating,and has achieved the expected results. It effectively promotes the informatization of spatial data collection,data management and updating in the implementation process of disaster risk spatial data col-lection and updating,and improves the efficiency and quality of field work.
