[A minimum medical GIS database (MMDb) for Europe].
Geographic information systems (GIS) and remote sensing (RS) technologies are being used increasingly to study the spatial and temporal patterns of some parasitic diseases of medical and veterinary importance. At the same time, the incorporation of GIS in this field shows the scarcity of the data and images available, which sometime discourage researchers that still look at GIS as a system too difficult and unusable for medical study. Aware of this problem and supported by success of earlier MMDb's for Africa, Asia and South America, the authors' aim is to construct and offer an MMDb for Europe. The initial MMDb is composed with vector images covering an area situated from -11 degrees-70 degrees N to 58 degrees-30 degrees E. Specifically, data layers include: a) Global Moderate-Resolution Imaging Spectroradiometer (MODIS) Normalized Difference Vegetation Index (NDVI) 16 days at 250 m spatial resolution designed to provide consistent spatial and temporal comparisons of vegetation conditions, supplied in the MMDb as seasonal and annual composite images from 2000 to 2003, b) MODIS Land Surface Temperature (LST) calculated from daytime and nighttime observations at 8 day intervals at 1 km spatial resolution, supplied in the MMDb as seasonal and annual composites images for day (maximum) temperatures, night (minimum) temperatures from 2000 to 2003, c) GTOPO30 Digital Elevation Model (DEM) at 1 km spatial resolution, d) United States Geological Survey (USGS) Land use/land cover scheme, e) USGS actual and potential evapotranspiration supplied for all 12 months as a grid at 50 km spatial resolution, f) USGS precipitation showing the amount of rainfall for all 12 months supplied as a grid at 50 km spatial resolution, g) USGS shapefiles of administrative and political boundaries, cities, towns, villages, lakes, rivers, streams, road, railroads and more. The MMDb projection will be in geographic latitude-longitude, decimal degree format. This global format is most commonly used for public access map database resources and can be readily re-projected as needed for compatibility with various national mapping systems. There is no "required" software, and end users need only common commercial GIS software packages that have mutual import-export functions. Additionally, the MMDb is meant to be a dynamic resource that end users may improve and modify with other regional data.
