BTV spread in Europe and predictors - SpatialData

Rasters used to compute resistance distances for the manuscript: Jacquot, M. , Nomikou, K., Palmarini, M. , Mertens, P. and Biek, R.(2017) Bluetongue virus spread in Europe is a consequence of climatic, landscape and vertebrate host factors as revealed by phylogeographic inference. <i>Proceedings of the Royal Society of London Series B: Biological Sciences</i> <br> - Climate data are all averages over 15 years (from January 1998 to December 2012) of monthly averages from: European Centre for Medium-range Weather Forecasts http://apps.ecmwf.int/datasets/data/interim-full-mnth/ <br> - Mean and standard deviation of elevation were obtained from: Global Multi-resolution Terrain Elevation Data (GMTED 2010) from the United States Geological Survey http://eros.usgs.gov/#Find_Data/Products_and_Data_Available/GMTED2010 <br> - Low- Mid- and High-elevations rasters were derived from the mean elevation one. <br> - Livestock densities were obtained from Food and Agriculture Organisation http://www.fao.org/ag/AGAInfo/resources/en/glw/GLW_dens.html <br> - The cattle density raster was used to generate the terrestrial habitat/land cover raster (Habitat vs non habitat areas).
