Abstract

Decision making is not a one-time process. On the contrary, it is a process that consists of several activities that occur and compete at different times (Laudon & Laudon, 1998). Such activities include: understanding the problem, designing possible solutions, choosing the ideal solution and finally implementing the chosen solution. In order to be able to carry out these activities, it is necessary to provide decision-makers with reliable and timely information. In any country, whether developed or in the process of development, as is the case of Mozambique, decision-makers need adequate information for decision-making on urban and environmental problems, etc. Authors such as Heywood et al (1998), Laudon and Laudon (1998) and Saugene (2005), consider the decision-making process as not easy and recognize, however, the need to define viable mechanisms that can help in a way faster and more efficient such process in different areas of society. Some of these mechanisms suggested by Laudon and Laudon (1998) consist in the development of decision support systems such as DSS, GDSS2 and ESS3. Knowledge of the space we live in has always been of great value to humanity. A few centuries ago, geographic information was imprecise, poorly organized, and unavailable. These limitations are no longer verified today, as for many regions of the planet there is abundant geographic information, obtained through methods that guarantee its accuracy. When decision making involves variables related to geographic issues (where, how, when, how long does it take, what is the distance, etc.), Geographic Information Systems (GIS) become an extremely high potential to aid in decision making. of decision (Abler, 1988)
