Rapid and auxiliary decision system of earthquake emergency based on QGIS

In order to solve the limitations of traditional GIS system on the popularization and deployment of earthquake emergency decision-making system due to large resource occupation, high deployment environment requirements and high software license fees. Based on QGIS open source desktop geographic information system, using earthquake impact field calculation model, casualty calculation model and rescue force calculation model, this paper adopts C / S structure to develop a comprehensive information system integrating automatic earthquake triggering, earthquake damage assessment and auxiliary decision-making, so as to expand the field of earthquake emergency service,better provide earthquake information technology services for governments at all levels and the public.
