The weighted linear combination (WLC) technique is a decision rule for deriving composite maps using GIS. It is one of the most often used decision models in GIS. The method, however, is frequently applied without full understanding of the assumptions underling this approach. In many case studies, the WLC model has been applied incorrectly and with dubious results because analysts (decision mak...

This paper presents a prototype of a simulation model based on cellular automata (CA), and multicriteria evaluation (MCE) and integrated with GIS. Speci® cally, a method, analytical hierarchy process (AHP), of MCE is used here to derive behaviour-oriented rules of transition in CA. A t̀ight’ integration strategy is adopted, which means that the modules of MCE and CA are written in the C programm...

Thematic map symbol is a basic component of thematic map language and it plays an important role in expressing the thematic content. However, the extensity of users leads to the diversity and complexity of the thematic symbols and expression methods, and most of the thematic maps do not have a fixed format and norms like topographic map. At the same time, we can not require all the users to be ...

This paper presents a software development approach to customize the GIS software ArcGIS (by ESRI) for spatial decision support. For the case study, example data of the Quémé catchment in Benin (Africa) is used to program such a system which will be used to plan the establishment of potential small water reservoirs. Therefore, a new user menu in ArcGIS is introduced which allows (i) the integra...
