GIS based Planning Support System

Glasgow: GIS as planning support system and decision support

system (2006)

The idea to use GIS as planning and decision support system in the scheme design process for the regeneration of the Glasgow Canals was incorporated because of the large number of factors that played a role in the decision process. Any instrument that would provide the chance to represent data, perceive the site from different perspectives and display different development options was considered valuable, so the team gave it a try. The GIS design process involved these steps:

Parametrics and GIS model for decision making

The design of a digital database and the assessment of existing resources is undertaken parallel to traditional analysis commissioned to specialised multi-disciplinary consultants. Some 40 different parameters were selected to study the development area on the feasibility of potential functions. As a result of the study, models displaying hotspots with best conditions for the development of industrial, residential, public, retail and mixed infrastructure, as well as for green and amenity space were generated. The model identifies existing features on site, such as zoning, functions, mobility conditions, public infrastructure, densities, heritage, canal related qualities, etc, and these are individually surveyed on their relevancy to each potential function. Special attention is dedicated to areas which lack fundamental conditions to qualify as attractive environment for private investment. conditions for green areas The area has been occupied by mainly business and industry, especially in the vicinity of the canal. Quite a large proportion of the development zone does not deliver anymore adequate conditions for industry (s. below), however the quality of green space is stressed by the model (s. above). conditions for business infrastructure Many vacant sites are located in areas with good conditions for public infrastructure. This opportunity was as considered in the proposed scheme. conditions for public infrastructure The extension of areas with required conditions for residential use is not surprisingly low. The area has been widely known for having the worst social conditions in Scotland since the decline of the industrial era in the early 1980s in Scotland. conditions for residential infrastructure In contrast to the reduced opportunities for residential use exclusively, the areas with best conditions for mixed use are extensive. This fact was perceived as well for the development of the design scheme and is understood as the most viable option. conditions for mixed development The extensive potential for retail can be well applied in the proposed mixed infrastructure, which foresees shops and business in lower floors and residential use in upper floors. conditions for retail development

Subtracting the sum of the values of the new conditions to the values of the existing conditions it was possible to measure possible impacts. impact retail development The difference of conditions for retail development make it clear that it can work best in certain areas only, unless it is incorporated in mixed development. Mixed development has best chances to deliver desired impact extensively. average impact of development Average values were also calculated to measure average impact.
