Data details

Name High Resolution Settlement Layer (HRSL)
Note The High Resolution Settlement Layer (HRSL) provides estimates of human population distribution at a resolution of 1 arc-second (approximately 30m) for the year 2015. The population estimates are based on recent census data and high-resolution (0.5m) satellite imagery from DigitalGlobe. The population grids provide detailed delineation of settlements in both urban and rural areas, which is useful for many research areas—from disaster response and humanitarian planning to the development of communications infrastructure. Data are available at https://ciesin.columbia.edu/data/hrsl/#data and they includes the population surfaces, metadata, and data quality layers. The population data surfaces are stored as GeoTIFF files for use in remote sensing or geographic information system (GIS) software. The archives include: a pop GeoTIFF that represents the number of persons estimated to live in each pixel, a settlement GeoTIFF that is a mask representing pixels within which one or more buildings was detected with a value of 1, and a shapefile depicting source imagery date and cloud cover percentage.
