    • Zwischenstadt (1997) - ‘Where we live now’ (Sieverts, T. 2008) Challenge the Future @ BEYOND THE EDGE - Melbourne 2013 SpatialPlanning &Strategy 7/29 7/20
    • Città diffusa - Veneto - Italy - (Secchi, B. & Viganò, P. 1990) Challenge the Future @ BEYOND THE EDGE - Melbourne 2013 SpatialPlanning &Strategy 8/29 8/20
    • Tyrol City - Austria - (Andexlinger et Al. 2005) Challenge the Future @ BEYOND THE EDGE - Melbourne 2013 SpatialPlanning &Strategy 9/29 9/20
    • learning from The EU/OECD - Urban rural Typology Major Limitations Focus on living population - missing out the working population. No consideration of functional relations (i. e. commuting) and infrastructure that facilitates these relations. Administrative boundaries as aggregation units. Major Advantages Easy to replicate. All necessary data is publicly available. Challenge the Future @ BEYOND THE EDGE - Melbourne 2013 SpatialPlanning &Strategy 16/29 16/20
    • bringing TiB on the Map - learning from other classifications Urban Morphological Zones (UMZ) based on CORINE land cover classification Primarily used to assess land cover change and the extend of urban growth (sprawl). Resolution 100 m pixel - UMZs are defined as built-up areas lying less than 200 m apart. Following core land cover classes: • ‘Continuous urban fabric’ • ‘Discontinuous urban fabric’ • ‘Industrial or commercial units’ • ‘Green urban areas’ and port areas - airports and- sport and leisure, if they are neighbours of the core classes. and road and rail networks and water courses, if they are located within 300 m. and forest and scrub areas, if they are completely encircled by one or more of the four core classes.

    • bringing TiB on the Map - learning from other classifications Peri-urban Land Use RELationships – Strategies and Sustainability Assessment Tools for Urban – Rural Linkages (PLUREL) European integrated research project within the European Commissions sixth framework programme. (2007 -2011) Urban area (continuous & over 20,000 population) Peri-urban area (discontinuous & over 40 persons / hectare) (a) Mono-centric settlement pattern City centre Inner urban Suburban (text book version) Urban fringe Urban periphery Built up area Rural hinterland Functional Urban Area Rural-urban-region Multiple combinations of urban & periurban areas Challenge the Future (b) Poly-centric settlement pattern (semi-realistic version) Peri-urban areas as ‘discontinuous built development, containing settlements of less than 20,000, with an average density of at least 40 persons per km2 (averaged over 1 km2 cells)’ (Piorr et al., 2011: 10) . Together with the urban area (continuous and cities with over 20,000 population) and the rural hinterland (less than 40 inhabitants per square kilometer) they form the rural-urban region (Piorr et al., 2011:25). @ BEYOND THE EDGE - Melbourne 2013 SpatialPlanning &Strategy 19/29 19/20
