ESTIA-SPOSE builds upon the experience accumulated by its predecessor ESTIA project and intends to develop Actions for a Spatial Planning Observatory in Southeast Europe, based on an integrated system of territorial indicators fully compatible with the approach of ESDP and ESPON. This system of indicators will be tested in a series of pilot applications in selected sectors and areas with the aim to promote both conceptual understanding and operational compatibility among the existing national spatial planning traditions. The project has three main components: - The Territorial Indicators System (TIS) is the conceptual and methodological component of ESTIA-SPOSE. The construction of an integrated territorial indicators system (TIS) is the most decisive factor for the establishment of a SPOSE. The base for the construction of TIS is the overall framework and the incoming results of the European Spatial Planning Observatory Network (ESPON). - The Pilot Applications of Indicators (PAI) in selected sectors and areas is the empirical component of ESTIA-SPOSE. The applicability of the TIS will be tested in real terms. - The Spatial Planning Observatory Platform (SPOP) intends to establish a more permanent network of agencies of spatial planning and development that will support the operation and discuss all conceptual, methodological and practical aspects of SPOSE based on TIS and PAI in ESTIA-SPOSE space. Expected Results: The main objective of ESTIA-SPOSE is to enhance the ability of the South-Eastern European countries to collaborate in spatial development and planning issues at transnational level through enhancing their individual and collective ability to collect, elaborate and analyse spatial data, similar to the ESPON program. The ESTIA-SPOSE project is establishing a network of institutions that operates on a common spatial planning observatory platform using a system of common indicators. The planned activities are: - The elaboration of a territorial indicators system, adapted to the South-Eastern European Space, - The pilot application of indicators focusing in NUTS III areas including major cities and development corridors in NUTS II, - The establishment of a more solid structure of a Spatial Planning Observatory Platform (Network of National Focal Points), complementing ESPON and including the Western Balkan area, - Documentation including reports and a comprehensive database allowing for more cooperation, - Meetings and workshops promoting the exchange of information and the necessary conceptual understanding and joint agenda for future cooperation, - A final conference for scientists, officials and politicians from all ESTIA space and neighbouring CADSES countries.
