Design and Implementation of Mobile GeoSpatial Information System for Public Health Emergency

As mobile devices like personal digital assistant (PDA) or handheld PC (HPC) are rapidly developing and the wireless Internet is increasingly used, interests in the mobile geospatial information system are gradually expanded. Nowadays, the outbreak of emergent public health events can be heard more often than before and make lots of people ill in a short time. How to deal with the events much more rapidly and efficiently are the main factors needed to be considered. With the development of mobile devices and wireless network, according to the characteristics of emergent public health event, the authors have designed and implemented a mobile geospatial information system based on PDA for public health emergency. The platform integrates the technologies of geographic information system (GIS), Global Positioning System (GPS), global system for mobile communication (GSM) and general packer radio service (GPRS). Based on platform, the paper conducts an experimental case study of HFRS (hemorrhagic fever with renal syndrome) fieldwork, and test the effectiveness and usefulness of field survey based on mobile collaboration.
