This readme explains how to recreate the data from Edmonds et al., (2020) 

Download the following datasets and run the scripts

(1) Place each geotiff raster in its own directory

(2) Place DeltaPolygons.shp in the same directory as the all subdirectories

(3) Place Edmonds_etal_DeltaPopulationExtraction.m and DeltaPopulationCalculation.m in the same directory as all the subdirectories containing the geotiffs

(4) Run Edmonds_etal_DeltaPopulationExtraction.m to extract the data from the geotiff rasters

(5) Run Edmonds_etal_DeltaPopulationCalculation.m to calculate the population and area statistics per delta
