Study on collaborative biohazard risk assessment system integrated with mobile GIS

This article summarizes related factors about biohazard events, and extracts the main factors to determine the main parameters of agent spread model and hazard assessment model. Mobile terminal (PDA) is used for data acquisition and model calculation, in the mean time a variety of methods are adopted for collaborative communications with server station, ensuring the consistency of models and datas. The map of national administrative divisions, rivers and other relevant factors are incorporated to realize the dynamic visualization of models, and establish the whole system of biohazard risk assessment models. This system improves emergency response capacity of biological hazards, and runs steadily and powerfully during working.
