2 Preamble: Who is EAGLE? EAGLE = EIONET Action Group on Land Monitoring in Europe Participants are Land Monitoring experts and Representatives of National Reference Centres (NRC) for Land Cover in the EEA s EIONET (European Environmental Information and Observation Network) Established in 2009 as self-initiative Independent from political interests Open membership based on own commitment Firstly no external funding, meanwhile supported by EEA funding Folie 2

3 Content Background and Motivation Criteria and Structure of Data Model Howtousethematrix Summary Results and Outlook Folie 3

4 Background and Motivation HarmonisationandIntegration ofdifferent datasourceson land cover and land use would require: Comparable or clearly separable definitions Common synchronized time/interval of data capture Comparable minimum mapping units Similar data quality Folie 4

5 Background and Motivation Many applications of LC/LU data lead to various different classification systems Mixture of LC and LU classes Specific fields of work cause fous on thematic categories Lack of comparability between nomenclatures hamper exchange of information between data sets National institutions are surrounded by National requirements Pan-European requirements (Europ. Commission, DGs, EEA, Eurostat) Folie 5

6 Klassifikation / Interpretation: Was war doch gleich... Wald, Gehölz, Baumgruppe? Kronendichte, Anzahl der Bäume, Stammumfang Mindestflächengröße / -breite Nutzung: Forst, Waldweide, Friedwald, Erholung Funktion: Habitat, Lawinenschutz, CO2-Senke Brache? Ehemalige Nutzung (Landwirtschaft, Wohnen, Industrie, etc.) Wie lange ungenutzt, 1 / 2 / 5 / 10 Jahre? Gartenland/Schrebergärten? Nutzung zur Erholung, Freizeit, Landwirtschaft, Selbstversorgung Bergbaufolgelandschaft / Renaturierung Grassland: landwirtschaftl. Nutzung oder Halde? Folie 6

7 Classification and Interpretation Same term different meaning Same content different name + difference in interpreting the class definitions or tolerance of class definition => Comparable/ Non-comparable data? Folie 7

17 Outcome of EAGLE concept EAGLE Matrix Excel Spread Sheet Matrix elements in columns Classes to be analysed in rows EAGLE Model UML model Enterprice Architect Connected to INSPIRE data specs on LC Folie 17

18 Structure of the EAGLE matrix Information on landscape described with three separate 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. Folie 18

24 Example: wetland Land cover components (LCC): Standing water body Reeds Land use attributes (LUA): none, recreational Reed harvest Barbara Kosztra Further Characteristica(CH): Ecosystem type = inland marsh Salinity < 0,1% (fresh water) Water regime = perennial Folie 24

25 Example: rural settlement Land cover components (LCC): Conventional buildings Trees, broad leaved Herbaceous plants Open sealed surfaces Land use attributes (LUA): Permanent residantial Agriculture, own consumption Road network Further characteristics (CH): Soilsealingdegree=35% Built-up pattern = discontinuous, single houses B.

32 Summary The Eagle concept LC/LU Workshop, INSPIRE Conference 2015, Lisboa Instrument for semantic analysis of class definitions (inconsistencies: overlaps, gaps), not a new classification system, but vehicle for semantic harmonisation and transformation, is INSPIRE compliant, can provide flexible framework for future mapping initiatives, helps to avoid redundant data capture, applicable on raster or polygon data, follows principle of integrating bottom-up/ top-down approach in the European land monitoring process, supported byeea, observed byeurostat Folie 32

33 Results and Outlook LC/LU Workshop, INSPIRE Conference 2015, Lisboa Results: Explanatory documention of EAGLE concept Fine tuning of matrix and model UML data model (incl UML chart) UpcomingEvent: GIO closing event , EEA, Copenhagen Tasks ongoing& ahead: Semantic testing of EAGLE matrix EAGLE matrix population and comparison tool Physical data base Folie 33
