The Global Healthsites Mapping Project is an initiative to create an online map of every health facility in the world and make the details of each location easily accessible. The aim of this website is the long term curation and validation of health care location data. The healthsites.io map will enable users to discover what healthcare facilities exist at any global location and the associated services and resources. Through collaborations with users, trusted partners and OpenStreepMap the location and contact details of every facility will be captured and the data made freely available under an Open Data License (ODBL). When a natural disaster or disease outbreak occurs there is a rush to establish accurate health care location data that can be used to support people on the ground. healthsites.io map aims to reduce the time wasted in establishing accurate and accessible baseline data.
