This paper presents the problem ofselecting route to connect two locations in Baghdad city; Alkadomiyah and Algria'at. Four alternatives were investigated using a multi criteria approach and spatial decision support system, (SDSS) that will assist a decision-maker, to select the optimal route fora new road path. In ARCGIS 9.2, spatial analysis has been used to carry out the searchstrategy. In general, the goal of this study is to develop a (GIS) - based model todetermine suitable route. Therefore, the required data for the proposed model buildingwere identified by using, land use, transportation maps, aerial photographs andographic features then reviewed for model development requirements. Four factorswere considered; Geotechnical, Geometrical, social and economical factors for multicriteriaevaluation to select the best routealternative. ARC GIS 9.2 softwarewas usedforthe analysis and modelbuilding requirements.In actualizingtheaim,satelliteagesof the studyarea was providedwhile the land-usemapwas obtainedfromDesignOffice-AmanatBaghdad. The land-use overthe study area was classified intoeightdifferent classes. A Digital Elevated Model(DEM) over the study area wasdownloaded from the Global Mapper Software, used to derive the slope map over thearea of study and the Analytic Hierarchy Process (AHP) was used in weighting theions. Finally, the case study demonstrated that GIS based on multi-criteriaapproach is recognized to be used as a tool for the optimum route selection byconsidering the factors affecting on the decision-maker route selection. Furthermore,saving of money, time and effort.
