GIS module for urban expansion analysis

Summary:
A new tool for analyzing urban expansion and making urban forecasts, following different planning scenarios was developed.

The application was implemented relying on ARC-INFO functionalities (GRID module) and taking into account urban distribution derived by satellite in the studied area for a qualitative analysis of the phenomena and the model devising.

It relies on the definition of spatial "factors" - areas from which new urban growth could start - and "constraints" - areas where urban expansion is not possible/allowed - which "guide" the urban expansion spatial distribution. The selection and suitable combination of the factors and constraints layers is interactive and made by the user through a tailored interface. The final output is a map showing new built-up areas in the studied area taking into account the number of km2 to be built to respond to new population growth and the different planning scenarios (factors and constraints).

These final maps showing the impact of the different scenarios of urban expansion on a specific area could provide an useful tool to land use planners, also helping them to illustrate the results of different planning decisions to the public.

Direct benefits to the Planning Division (partner of the Consortium):
- check of the impact of different future scenarios on a restricted area considering the number of km2 to be built up to 2020;
- upgraded features and functions of its hardware and software equipment, being so able to directly manage all the outcomes of the project, also through a powered Geographic Information software.
