Land Cover Data at EEA CORINE Land Cover Soil Sealing Layer Urban Atlas Markus Erhard European Environment Agency (EEA) markus.erhard@eea.europa.eu 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)
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
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 e-mail. 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 CLC 1990 CLC CLC 2000 2006 CLC 2012 +
