We propose a characterization of axial maps by means of an extension of a local property which has been proved to describe the cell decomposition of the plane induced by line arrangements. This gives a discrete model which is more closely related to axial maps than the usual representation by...

One class of spatial problems is concerned with the location of facilities and the allocation of demand to them. A special case occurs in rural areas where a minimum workload may be needed to ensure the viability of a facility. Where a facility does not meet this threshold workload, demand may...

The 'neotraditional' town is receiving increasing popular, professional, and scholarly attention. Its proponents argue that its design features provide a viable alternative to the modern city and its sprawling suburbs. That critical and normative argument is assessed in this paper by means of...

The problem of formal classification in urban morphological studies is addressed and a method of profiling the distinctive form of urban neighbourhoods is presented. The approach searches for regularity of pattern in tessellated surfaces of cities and constructs textural signatures that can...

Research was carried out with two dates of thermal satellite imagery and field climatic data in six high-rise housing estates in Singapore to investigate the relationship between satellite-derived values and the urban microclimate. GIS techniques were used to register the image data for two...

The problem of selecting parcels of land for inclusion within a protected reserve is formulated as a 0-1 programming model. The formulation addresses the objectives of minimizing cost and maximizing reserve area, while providing buffer zones around interior or core areas and promoting contiguity...
