1. Land Cover Data at EEA CORINE Land Cover Soil Sealing Layer Urban Atlas
Markus Erhard European Environment Agency (EEA)
1. Introduction:
    EEA mission & tasks
    EEA network (EIONET) & priorities
2. Monitoring, assessment and reporting related to Water
    EIONET Water Monitoring Network
    Assessments (LARA & water accounts)
    Data platform (WISE) & data needs
3. Outlook (link to GEOLAND activities)
    Water quantity (irrigation)
    Quantification of pressures on water quality
    Structural changes of water bodies (hydropower, shipping, fragmentation)
    Anthropogenic and natural forcing (climate change, land-use changes (link to other priorities) etc)
Points are presented and discussed to show open issues which might be of interest for the Geoland consortium (data needs,harmonization, gaps, visions)

2. Why Land Cover Monitoring
Multi-functionality of land – link to other sectors  urban and landscape planning, water, soil, biodiversity, climate change, air quality, natural hazards etc.
Monitoring, assessment and reporting (continuous observation of environmental changes over space and time)  indicators, reporting obligations etc.
Decision support, policy effectiveness  need for action

3. Environmental change vs. technical progress
… and mapping
Environmental change vs. technical progress
Hand made maps
First GIS
GIS electronic mapping
Web-based
Information systems
First few years, no technical infrastructure in place
Requests and deliveries were sent by post on paper and copied for distribtuion
These working methods were replaced by . To begin with there were many problems with file formats
Data deliveries were put in data bases, mostly maintained by the ETCs
For the past few years, data have been delivered from most countries directly into the central data repository of Reportnet where they can be retrieved by many users

4. CORINE Land Cover (CLC)
reference years: 1990 / 2000 / 2006 / image resolution: 10 x 10 m – 30 x 30 m MMU (Minimum Mapping Unit) 25 ha (5 ha change detection)  land cover classes / accounts

5. CLC 2006 Germany and Berlin (aggregated maps)

6. High Resolution Layer (HRL) soil sealing / imperviousness
reference years 2006 / 2009 / image resolution 20 x 20 m MMU (Minimum Mapping Unit) 1ha  sealing and density (0 – 100 %)

7. Continental Component CLC 2012 + 5 High Resolution Layers (HRLs)
 20 x 20 m resolution for validated 100 x 100m (1 ha) grid cells
artificial surfaces: imperviousness layer (0-100%) (former soil sealing)
forest areas: foliage type (coniferous, deciduous, mixed) and crown coverage (0-100%)
agricultural areas: mapping of permanent grassland
wetlands: mapping of wetness
water surfaces: small water bodies complementary to WFD and reference data

9. Statistics Changes in imperviousness in Europe:
Increase of sealed area 2009 towards sealed area 2006 in km² per country
Sealed area in % of total country area
Increase of sealed area 2009 towards sealed area 2006 in % per country
sealed area change 2009 towards sealed area 2006 in % per country
 sealed area 2006 = 100 %
 diese prozente sind zusätzlich dazugekommen
sealed area change 2009 in km per country
 zusätzliche Fläche in 2009 in km²
sealed area 2009 in % of total country area
 verbaute fläche der Landesfläche gesamt
sealed area = alles ab 1% versiegelung

10. Urban Atlas (DG Regio)
reference years 2006 / image resolution (2006) 2.5 x 2.5 m MMU (Minimum Mapping Unit) 0.25 ha  major cities (> pop.) currently ca. 120 cities (> 300 cities envisaged)

15. Local component – Urban Atlas
GIO Land Services
3 components:
Local : zooming on ‘hot spot’ (e.g. urban atlas, protected areas, coastal areas)
Continental: pan-European products (Corine 2012, 5 HRLs soil sealing, forest, agriculture, wetland, water)
Global: bio-physical parameters (Essential Climate Variables (ECVs), food security (Africa) etc.)
Local component – Urban Atlas
EU component - CLC
Global component – ECV*s
