CONTENT 1. Given situation 2. Criteria for data model 3. EAGLE concept and structure 4. Next steps and future perspectives 5. HELM Road Map 19.06.2014 HELM / EAGLE, INSPIRE Conference, Aalborg 2
Given situation in European Land Monitoring Diverse applications of LC/LU information => many classification systems and nomenclatures. Focus on different aspects of LC/LU, Different data collection methods, Different scales, Narrow tailored-to-purpose definitions, Incomparable precision/degree of class definitions, Lack of completeness for either LC and/or LU information. 19.06.2014 HELM / EAGLE, INSPIRE Conference, Aalborg 3
Working conditions: Where we come from, what s ahead? Drivers for design of land related classification systems so far Specific user needs Constraints Budget constraints Technical constraints Data access constraints => Typical example: CORINE Land Cover Enhanced data situation: Data access: SENTINEL generation ahead, opened LANDSAT archives, INSPIRE open data policies Technical advance: Data storage and processing capacities, spatial resolution 19.06.2014 HELM / EAGLE, INSPIRE Conference, Aalborg 4
Criteria for LM data model Conceptual point of view Separation between LC and LU information (both can have different change dynamics), Mutually exclusive and comprehensive list of land cover components, Applicability on different scales, Applicability on national and European level Semantic translation between different classification systems, INSPIRE compliance, Support the bottom-up approach, Integration of parameters, Flexibility in structure for adding new model elements. 19.06.2014 HELM / EAGLE, INSPIRE Conference, Aalborg 5
Criteria for LM data model Thematic content point of view Data model should store information about soil sealing degree, crown cover density, habitats / ecosystem types, crop types, land management forms and cultivation patterns, spatial pattern, status, temporal patterns, transitional phenomena Among others 19.06.2014 HELM / EAGLE, INSPIRE Conference, Aalborg 6

Content of EAGLE matrix Information on landscape described with three separate main blocks I.) LAND COVER Components LCC Abiotic (Artificial + Natural), Vegetation, Water Surfaces => no classes, but elements II.) LAND USE Attributes LUA Agriculture, Forestry, Residential, Transportation etc. III.) CHARACTERISTICS CH further information on: spatial pattern, bio-physical parameters, ecosystem types, cultivation measures, land management practices etc. 19.06.2014 HELM / EAGLE, INSPIRE Conference, Aalborg 8
I. Land Cover Components [LCC] Describe real landscape elements from pure LC point of view. (Read Matrix from top to bottom.) 19.06.2014 HELM / EAGLE, INSPIRE Conference, Aalborg 9
II. Land Use Attributes [LUA] Describe territory from pure LU point of view, according to function and socio-economic purpose, linked to INSPIRE (extract shown only) 19.06.2014 HELM / EAGLE, INSPIRE Conference, Aalborg 10
III. further Characteristics [CH] Characterize landscape with additional properties, flexible extendable list (extract shown only) 19.06.2014 HELM / EAGLE, INSPIRE Conference, Aalborg 11
CLC classes Structure of EAGLE Matrix I. LCC block II. LUA block III. CH block 19.06.2014 HELM / EAGLE, INSPIRE Conference, Aalborg 12

How to use EAGLE matrix: Describing wetland with EAGLE model Land cover components (LCC): Inland water Reeds Land use attributes (LUA): Nature protection site Recreational area Further characteristics (CH): Ecosystem type = inland marsh Recreational area Salinity = 0% (fresh water) Water regime = perennial Barbara Kosztra 19.06.2014 HELM / EAGLE, INSPIRE Conference, Aalborg 15
How to use EAGLE matrix: Describing village with EAGLE model Land cover components (LCC): conventional buildings broadleaved trees herbaceous plants, open sealed surfaces Land use attributes (LUA): permanent residential agriculture/production for own consumption road network Further characteristics (CH): soil sealing degree = 35% built-up pattern = discontinuous, single houses Gyorgy Büttner 19.06.2014 HELM / EAGLE, INSPIRE Conference, Aalborg 16
EAGLE key messages EAGLE matrix as semantic translation tool between classification systems and for semantic analysis of inconsistencies (gaps/overlaps) within or between classes EAGLE data model as conceptual basis for future European land monitoring system => COOKBOOK (list of ingredients): EAGLE concept is not another classification system but descriptive vehicle for harmonization of LC/LU information between national & European levels 19.06.2014 HELM / EAGLE, INSPIRE Conference, Aalborg 17
What is HELM? FP7 project 2011-2013 Participants: authorities and experts in the field of land monitoring from 17 European countries Objectives: - Collection of best practices of land monitoring - Roadmap towards Harmonised European Land Monitoring
Integration scheme of European Land Monitoring Framework [C O P E R N I C U S] European & Global Level CLC Urban Atlas HR Layers LPIS LUCAS EAGLE concept National & Sub-National Level National (A) Land Monitoring Regional (a) Land Monitoring National CLC Regional (b) Land Monitoring National (B) Land Monitoring 19.06.2014 HELM / EAGLE, INSPIRE Conference, Aalborg 19
Preconditions Administrative matters Full & contiunuous user consultation process from national to European level Existence of (European) stakeholder who takes the lead and national counterparts Sustainable funding mechanism and legal framework Open data policy Long-term planning pave way for short-term actions
Preconditions Technical/Scientific matters INSPIRE compliance Development of modern techniques to handle variety among countries A dual track system where MS can proceed differently according the availability of relevant data Semantic/nomenclature data model EAGLE data model Polygons/grids Geometric GRID approach Timing/repeat frequencies of data gathering synchronisation (LUCAS/CLC) Backwards compatibility to CORINE LC Provision of guidance and common tools (a cook book )
The HELM Roadmap Production of Pan-European datasets should be based on nationally produced LM data to ensure quality and compatibility of the data as well as resource-efficiency Users are most effectively be involved through continuous collaboration and participation Balance between European level harmonization and autonomy of MS must be preserved Copernicus programme provides a platform to put HELM concept into action (WP 2014 states support EAGLE/HELM future development ) Horizon 2020 provides a potential framework for funding of further development towards implementation of HELM roadmap
