Sustainable management of rural landscapes: application of new routines implemented on GIS for modelling visual relationships

J. Hernández, L. García, F. Ayuga


The purpose of this paper was to introduce a spatial decision support system (SDSS) for site selection of new buildings in rural landscapes. It is based on Geographic Information Systems (GIS). This process consists of a twostage methodology: namely, land suitability mapping, followed by visual interpretation of potential sites. The SDSS is part of integrated computer software which can perform both functions, being specifically developed for this purpose and registered as GISCAD 2.0. This is a programme created in ARC/INFO Macro Language (AML) programming language. This is the means to generate macros and routines in ARC/INFO versions 7 and 8 for the consecutive execution of linked commands. As regards the computer routines, they are more than a mere concatenation of orders to be carried out successively by ARC/INFO. Some of them, such as COMPOSITION.AML, BACKGROUND.AML, CAPACITY.AML, SETTLE.AML and INTEGRATION.AML, are actually a logical analysis system which provides GISCAD 2.0 with a decision-making capacity according to the information supplied. At present these routines are being worked into a fully efficient system incorporating the ability to learn from the decisions taken, and for this information to form part of the initial data for the following calculation cycle.
