1 Urban Morphological Zones v An improved dataset for urban analysis Roger Milego i Agràs ETC-TE Workshop on Land Accounts and Urban Morphology Bellaterra, 12th July 2006

2 A set of urban areas laying less than 200m apart Urban areas defined from land cover classes contributing to the urban tissue and function. –111 – Continuous urban fabric –112 – Discontinuous urban fabric –121 – Industrial or commercial units –141 – Green urban areas –123 (Port areas), 124 (Airports) and 142 (Sport and leisure facilities), if they are neighbours to the core classes or to one of them touching the core classes. Enlarged core classes –122 (Road and rail networks) and 511 (Water courses), when neighbours to UMZ 1st step, cut by 300m buffer. –Forests & scrub (311,312,313,322,323,324), when they are completely within the core classes. UMZ definition Workshop on Land Accounts and Urban Morphology, UAB, 12th July 06 Core classes

3 Procedural steps 1) CLC2000 reclassification Core classes Ports, Airports and sport facilities Transportation and rivers Forests & scrub VECTORISATION Workshop on Land Accounts and Urban Morphology, UAB, 12th July 06

4 Procedural steps 2) Addition of ports, airports and sport facilities to the core classes Core classes Ports, airports… Selection by neighbourhood (iterative process) Merge Enlarged core classes Workshop on Land Accounts and Urban Morphology, UAB, 12th July 06

5 Procedural steps 3) Addition of roads, railways and rivers to the enlarged core classes Enlarged core classes Roads, railways, rivers Selection by neighbourhood Clip by 300m buffer around enlarged core classes Workshop on Land Accounts and Urban Morphology, UAB, 12th July 06 Merge Enlarged core classes + roads, railways and rivers

6 Procedural steps 4) Addition of forest and scrub classes fully within the core classes Enlarged c.c. + roads… Forests & scrub Selection (fully inside core classes) Merge Workshop on Land Accounts and Urban Morphology, UAB, 12th July 06 Pre-UMZ rasterisation

7 Procedural steps 5) UMZ built-up: expansion and shrinking processes Workshop on Land Accounts and Urban Morphology, UAB, 12th July 06 Rasterised Pre-UMZ EXPANSION by 1 pixel (100m) SHRINKING by 1 pixel (100m) Vectorisation UMZ v. 2006

8 Attribute assignment Commune codes: intersection with EuroBoundaryMap Jan06

9 Attribute assignment Population figures: intersection with JRCs 2001 Population density grid (made by Javier Gallego). Result: population number within every single UMZ. CY,BA,MK,AL: population data from citypopulation.de for main cities (in general, above 5000 inhabitants)

10 Further steps UMZ denomination: i.e. based on main city or main cities. Other attributes addition. Linkage to statistics. Calculation of UMZ90 based on CLC90 revised. Calculation of changes between UMZ90 and UMZ2000. Workshop on Land Accounts and Urban Morphology, UAB, 12th July 06 THANKS!
