This dataset consists of GeoTIFFs, MBTiles, KMLs, PDFs, and shapefiles. Total dataset size is approximately 51GB. In this work, only the GeoTIFFs and shapefiles are utilized. The additional files are included in the archives provided on humdata.org and may provide useful information for others.
We have assembled a script and set of URLs to make it easier for individuals to download the data referenced in our work. We hope this makes it easier for individuals to reproduce our work, but also hope that it helps lower the barrier of entry for those interested in developing additional humanitarian tools.
Please be mindful of the bandwidth required to host this data by not unnecessarily or repeatedly downloading the data. To download the imagery and shapefiles run
