Theia Risks associated with infectious diseases SEC provides spatialized monthly surface water raster layers, derived from a time series of Sentinel-2 satellite images (from the year 2018), for Hwange, Gonarezhou and North Kruger National Parks in Zimbabwe.
Like vegetation, surface water availability is one of the main determinants of wild and domestic animal species such as buffalo and cattle in savanna environments. The ability to spatially characterize the seasonality of surface water availability at the landscape scale allows for the analysis and modeling of the two focal species respective movements, contact areas and potential inter and intra-species pathogen transmissions (foot-and-mouth disease and Rift Valley fever).
These spatialized raster data are used in the TEMPO project.
