The EDENext DMT has created three population proximity layers for 2005, 2030 and 2050. The layers are distributed as 1km GeoTIFFs at 1km.
The aim of this layer is to describe the population which is likely to visit each cell in the raster. By using this layer alongside geographic data of factors relating to disease risk it may be usefult to highlight high risk areas with areas of high surrounding population. Ergo highlighting areas where the risk of human contraction of disease could be at its highest.
The method to achieve this for each cell in the raster layer: a linear-distance weighting is applied to the surrounding cells the current cell is multiplied by 1 and the cells >30km away are multiplied by 0. All cells in between are multiplied by a multiplier between 1 and zero corresponding to this linear distance relationship. All the resultant values within 30km are then summed to give the Distance weighted population proximity index value for that cell.
The population numbers used for this dataset are STQ population projections from the ESPON2013 database. Please see the metadata file for more information on how this layer was created.
Please note this dataset in 433MB unzipped.
