GIS technology has functions of data storage, query, statistical analysis, simulation, decision making
and prediction, and can rapidly collect and process meteorological information, directly analyze, demonstrate
geographic information of disaster area and agricultural industry structure. Based on analyzing the links of GIS
technology in the typhoon disaster in application and its key technologies, this paper established the evaluation
system of agricultural losses by typhoon disaster based on GIS and virtual technology, realized the dynamic
simulation of typhoon information display, agricultural loss assessment, to provide straightforward, scientific support
for making the agricultural insurance policy, agricultural subsidy policy. |
