It is clear that geographic information systems (GIS) offer many new opportunities for both geographic research and planning practice. The problem is how to cope with these possibilities and how to resolve the various technical problems which beset the present generation of GIS. Two fundamental...

Remote sensing (RS) and geographic information systems (GIS) can provide essential support for each other's operations. RS can provide information on current and changed land-use cover for a GIS, and, more importantly, a GIS can provide an essential expert knowledge base to help automate the...

The composition system developed in a previous paper is implemented: compositions at lower levels of the composition system are enumerated by hand and by a Pascal program. Compositions at higher levels are developed by generating architectural languages -- that is, by selecting sets of 2 x 2...

Theoretical and experimental results from the implementation of a system for computer-aided floor-plan design are reported. The system is based on a potentially exhaustive search for solutions that satisfy user-specified constraints, but the paper concentrates on techniques for limiting and...

It is shown that it is always possible to construct an orthogonal floorplan satisfying the area and adjacency requirements of any vertex-weighted maximal planar graph which is its dual.

Previous research efforts demonstrate the use of location covering in the spatial structuring of central places within a single-good context. In a multilevel context, a mathematical programming approach is developed to the siting of central places for Christaller hierarchies. The primary model...

Design criteria for urban and regional information systems are outlined. An attempt is made to evaluate the nationally available statistical series in the United Kingdom in the context of those design criteria and some of the systems developed in British local government to counter the...

A color grammar that describes the composition and landscaping of Mughul gardens is discussed.

In this paper it is proposed that relevant information systems which support the activities of planning and decisionmaking must be based upon a thorough and clear analysis of the planning processes adopted. To this end, a general schema which identifies four key elements of a planning problem --...
