HERIT-DATA has defined a set of @indicators to collect data about tourism flows and is developing an @online platform to analyze this data. The platform will help policymakers, destination managers, cities and sites to anticipate and manage the tourism flows in a smarter way. An App will use this data and help visitors to better organize their visits. All these tools will be tested in @six pilot sites in Croatia, Bosnia-Herzegovina, France, Greece, Italy and Spain.
