Abstract:

Objective To establish the geographical information system（GIS） for schistosomiasis based on Google Earth. Methods The placemark, path, polygon, overlay and so on were added to Google Earth to establish GIS for schistosomiasis. Results The GIS for schistosomiasis had been established. The system included six modules, such as endemic area, river system, epidemic map, snail environment, new and recurrent snail environment, and acute schistosomiasis. Through operating the GIS, the real-time information of schistosomiasis could be viewed on the 3D map. Conclusion The GIS for schistosomiasis based on Google Earth was simple to learn, low cost and powerful, which was very suitable for basic schistosomiasis control station to use.
