  • The use of remote sensing and landscape metrics to describe structures and changes in urban land uses
  • California ; Image analysis ; Land use ; United States of America ; Urban area ; Urban density ; Urban environment ; Urban landscape
  • . Several important structural land-cover features are identified. For two test areas in the region, changes in the urban spatial land-use structure can be described and quantified with landscape metrics.
  • The study introduces a methodology using information on image spatial form to describe urban land-use structures and land-cover changes that result from urban growth. The analysis is based on spatial analysis of land-cover structures mapped from
  • digitally classified of aerial photographs of the urban region Santa Barbara, California. The results show a useful separation and characterization of three urban land-use types : commercial development, high-density residential, and low-density residential

  • Attention is often focused on institutional investors' motives for holding regeneration investments and on how they might be encouraged to put more money into inner-city areas. The paper argues that the impact of such an approach upon urban
  • regeneration may be limited. Independent developers embrace the challenge presented by fringe locations, mixed uses and the local urban culture, and translate these characteristics into development values. The AA. choose Manchester as an example.

  • Density gradients in Canadian metropolitan regions, 1971-96 : differential patterns of central area and suburban growth and change
  • Canada ; Demographic change ; Density gradient ; Distance from city centre ; Suburbanization ; Town ; Urban growth ; Urban population
  • Over the period, the majority of Canadian cities have undergone transition towards an increasingly decentralised urban form. The trends are quite diverse, pointing to fundamental differences in the respective importance of growth in central
  • and outer parts of the metropolitan area. The predominant trend has been towards suburban-style, low-density expansion, albeit with considerable intercity variation regarding changes in central area and suburban density.

  • A comparative analysis of the air quality management challenges and capabilities in urban and rural English local authorities
  • Across Great Britain 120 Air Quality Management Areas are in the process of being declared. The paper compares and contrasts the challenges facing urban and rural authorities in carrying out their responsabilities. Although urban authorities appear
  • to be facing greater and more complex air quality challenges, rural areas are not without their own air quality challenges. The hypothesis that urban authorities have more effective frameworks in place for tackling the challenges of air quality action planning
