UNESCO’s World Heritage Online Map Platform(WHOMP) is a Geographic Information System (GIS) developed with the support of the Government of Flanders (Belgium), aiming at the creation of a comprehensive and accessible geodatabase for World Heritage properties worldwide. This platform is hosted and managed by UNESCO which ensures that the data presented correspond exactly to the boundaries of the World Heritage properties and their buffer zones as inscribed in the World Heritage List, including any changes adopted by the World Heritage Committee after the initial inscription of a property. The World Heritage Online Map Platform is a monitoring tool to better manage and protect World Heritage properties. The Platform primarily serves States Parties to the World Heritage Convention, World Heritage site managers, World Heritage site communities and other heritage and non-heritage stakeholders (i.e., developers and urban planners). It is also intended to become an indispensable monitoring tool for the Advisory Bodies to the World Heritage Committee and for UNESCO as Secretariat to the World Heritage Convention.
