Geomatics becomes a major field of science facing challenges to assist medical informatics and health decision makers thanks to attractive concepts, methods and easy, user-friendly-way IT technologies. PoleSat_2018 presents a web-based graphical user interface with an embedded optimized and automated algorithm. It is primarily geared for geomatics non-specialists and allows computer simulations by modelling scenarios of hospital grouping and/or closure. The consultation, reflection, prospective views, offered in a very short time to policy makers will find a successful support for health planning strategic decisions.
