ADRIPLAN stands for ADRiatic Ionian maritime spatial PLANning and is a project funded by the European Commission – DG Maritime Affairs and Fisheries (DG MARE) under the theme 'Maritime Spatial Planning (MSP) in the Mediterranean sea and/or the Black sea'. The ADRIPLAN project will improve the ongoing process to develop MSP in the region, to overcome barriers of full participation of all neighbouring countries in the process and promote sound technically/scientifically based political decisions in order to promote a coherent transnational approach to the spatial planning of the marine seas. The ADRIPLAN project is implemented by 17 Partners from 4 countries of the Adriatic –Ionian Macroregion: 8 Scientific Partners and 9 Institutional Partners. ADRIPLAN data portal is available for searching and sharing knowledge, data, and information related to MSP in the project area. The geoportal wants to implement a system for data and metadata management (scientific and geographical, textual documents, tables, etc...). It can help users (stakeholders, administrators, scientists) to consult and exploit the scientific information provided by the ADRIPLAN partners.
