The parer introduces with specific objectives of recently started project “Linked Open Data for environment protection in Smart Regions” (LOD project) supported by Seventh Framework ENV.2013.6.5-3: Exploiting the European Open Data Strategy to mobilize the use of environmental data and information. The main concept of the project is to create a Linked Open Data (LOD) infrastructure (including software tools and data sets) fed by public and freely available data resources, existing sources for biodiversity and environment protection and research in rural and European protected areas and its National Parks. It is panned within the project to developed real proposals how to build a LOD infrastructure for biodiversity and environment protection in European protected areas that satisfy the requirements of four kinds of target users: public bodies, researchers, companies (also small and medium enterprises (SMEs)) and citizens. The LOD project will focus also on how LOD Initiative can be linked with INSPIRE directive, GEOSS Data-CORE, GMES, completed European scale GIS projects (like a Habitats project, which defined models and tools for managing spatial data in environmental protection areas), and external third parties, as well as how it can impact the economic and sustainability progress in European Environmental research and protection. The key elements of the project will be five target pilot projects in related areas (agro forestry management, environmental research and biodiversity, water monitoring, forest sustainability and environmental data re-use), where harmonization of metadata, improvement of spatial data fusion, as well as visualization and publish the resulting information according to user requirements will take place.
