E4warning_2021_Hospital Density_adminlevel2

Abstract: These maps of hospital density facilkities a are derived from the open source Open Street Maps (OSM). These are large datasets that underlie most of the satnav utilities and are continuously updated by members of the public. They are compiled by GEOFABRIK, and can be downloaded from https://www.geofabric.de. Health care data have been further enhanced by the Global Health Sites Mapping Project (https://healthsites.io).   The data consist of locations (“points of interest”) and building outlines, and so are made up of points and polygon which are stored separately in the OSM files. Each record has a series of descriptors (“tags”) such as ‘amenity’ which may include descriptions such as hospital . These tags are provided by the people who add the data to the maps and they are multilingual and very variable. Most records contain additional more generic tags that can be used to identify classes of locations like hospitals or pharmacies.   ERGO has taken the IO and OSM datasets, combined the polygon and point data, converted the polygons to points and removed any duplicates (where building outlines also have point location records), to produce and global datasets for healthcare and regional datasets for healthcare  locations covering Europe and its neighboring countries. Later these data were transferred to a tif file to density of hospitals into Admin Level 2 .
