Open Land Use Map is an initiative that has been started by the Plan4business project and that will be extended as part of the SDI4Apps project in the future. This service aims to create an improved worldwide land use map. The initial map will be prepared using the CORINE Land Cover, Global Cover dataset and Open Street Map. Contributors, mainly volunteers, will able to change the geometry and assign up-to-date land use according to the HILUCS specification. For certain regions more detailed datasets, if available, will be used as an update of the Open Land Use Map. The product is treated as Open Data and users will be able to download the data in a specified format and for a selected area. The paper introduces the technical and business aspects of Open Land Use Map app including the integration and harmonisation tools, sustainability plan and apps that accompany the entire platform.
