The goal of this paper is not to present outcomes of research, but rather present a new research plan in the use of chorems in geographic information systems. Created by R. Brunet, chorems are a schematic representation of a territory. Presently, geographic decision-makers are not totally satisfied by conventional cartography, essentially because they want to know where and what are the problem...

The paper seeks to highlight how the character and values of marginal landscapes can be considered examples of the “third landscape” and how they can enable the mapping of tangible and intangible change (and its relative effects) through the selection of appropriate spatial indicators. A Dynamic Spatial Decision Support System was constructed to help identify the complex values characterizing a...

The South African Weather Service (SAWS) operates a nationwide network of ground-based meteorologic radar stations (National Weather Radar Network), providing data continuity in some regions dating back to 1994, which is unique for southern africa. The incoming data is processed and archived using the TITAN software package[1]. Thematic digital maps are derived which can be accessed through the...

The use of renewable energy sources is often suggested to be a good solution for climate change and the dependency to fossil fuel. Biogas utilization is a one of these promising options that can mitigate these problems since biogas is produced by the fermentation of waste, so is rich in methane and has the same characteristics as natural gas. Biogas has increasingly been noticed in different co...

This dissertation consists of three essays that propose designs and theoretically-based evaluations of two novel decision support systems (DSS): a web-based spatial DSS (SDSS), a dialectic DSS (DDSS), and a comparative analysis of subjective and objective measures of system success in terms of decision process and outcome. In the first essay, a web-based SDSS that utilizes the latest advances i...
