• Creation of a high-resolution land cover/use map of urban areas
• Thematic classes based on CLC nomenclature
• More specific classes for built-up areas• Geometric resolution 1:10000• Minimum mapping unit 0.25 ha (in class 1
areas; 1 ha in other areas)
Main features

Selection of urban areas
• Compatible with Urban Audit definitions
• Larger Urban Zones (LUZ)
• Priority list of LUZs

Time frame
• First reference year: 2006 +/- 1 year• All LUZ expected to be mapped within 3
years• Update envisaged every 3 to 5 years
– Enhance comparability and reduce update costs by focusing on change analysis
• Aiming at next reference year = 2011– Compatible with census-related information and
Urban Audit

Use of results
• Take advantage of comparability with information from the Urban Audit
• Derive indicators at the level of Urban Audit cities, LUZs, sub-city districts (SCDs) or raster cells

Outlook
• First results (first series of cities on the priority list) during 2009
• Opportunity to test the development of relevant indicators and to explore their relationship with Urban Audit results or other data sources
