title: [Study on the geographic information system databases regarding the control of schistosomiasis in Zhongxiang, Hubei province, China].
abstract: OBJECTIVE
  Using geographic information system (GIS) and the remote sensing techniques (RS), we developed a schistosomiasis database and geographic distribution map in Zhongxiang city,Hubei province in order to display and analyze the endemic situation longitudinally after the water conservancy project is completed.
  
  
  METHODS
  Epidemiological data of schistosomiasis and the correlated climate and hydrology data for the last 30 years were collected and the relevant GIS databases were established under Artificial Neural Networks(ANN) and network training of Landsat TM images.
  
  
  RESULTS
  GIS database of schistosomiasis in Zhongxiang city, Hubei province and its vicinity areas were developed including 1 maps regarding the epidemic situation of schistosomiasis. The areas of snail distributing were 4.4 hm2, 8.2 hm2, 24 hm2, 130.4 hm2, 8.13 hm2 and 7.53 hm2, respectively.
  
  
  CONCLUSIONS
  The maps created by GIS database and RS techniques supported the complicated query on space and property, providing a new way in keeping,updating and analyzing available data. The techniques used should be able to provide evidence for the control of schistosomiasis to this water conservancy project.
