This report summarizes the INSPIRE-GMES workshop for land cover which took place in Madrid from June 29th to July 1st, 2009 was co-organised by IGN Spain (Spanish national mapping agency), CDTI (Spanish GMES National Coordinator) and the European Commission (DG Enterprise and Joint Research Centre). The objective was to discuss the development around the INSPIRE Directive 2007/2/EC (Annex II Land Cover and Annex III Land Use themes) and the GMES (Global Monitoring of Environment and Security) initiative in the field of Land Cover. This workshop was the first opportunity to bring together experts at various levels (European, National, Global) to define medium and long strategy for the future of European Land Cover (LC) and Land Use (LU) activities and to investigate possible approaches for harmonising information from various sources.

Dear Paul,
We are about to create sub-network of Cities and Regions in Poland, being connected to PLAN4ALL e-Contentplus project, There are actually two Affiliate Partners of PLAN4ALL Project in Poland, but due to big interest of selfgovernmental bodies we are wondering on usage of different data sources and classification methods while elaborating next generation apporach to land cover and land use in Poland.
It is obvious, that "land-use" term have evolved dramatically in last 20 years. First CORINE MMUs, were changed into much more detailed ones, and that really makes the difference for urban planners, if MMU has 25 hectares and is useless at regional planning level (500x500 m pixel), or 5 hectares (CLC2006 I believe ?), or 0,35 hectares like in European Urban Atlas - for 14 urban classes. But what 50 x 50 meteres MMU (European Urban Atlas MMU) means to local, urban planners ? Almost NONE. ZERO. Especially if You have, like the City of Wroclaw in Poland - 25 000 vector polygons, with assigned multi-attribute textual data, that can be search-through...Currently ca 45 cities in Poland have had either 15 cm pixel-based (digital cameras) orthophoto, or at worst (80 cm - 1 meter pixel) IKONOS 2005-2008 coverage.
With classification methods, using OBIA (Object-Based Image Classification), with classification of VHR Images with e-Cognition-based decision trees (like one of Christian Hoffmann from Geoville) - it is already possible to generate land-use at accuracy of settlement structures (1: 2000 - to - 1: 10 000 scales mapping), what we've done together in 2008. Now, we look forward to take the challenge of integration of INSPIRE and GMES at Regional Level.
I will keep you up-to date on our efforts.
