| Abstract | ||
| Route planning analysis in Geographical Information System (GIS) provides strong decision support for users in searching optimal route, finding the optimal path is an important advanced analysis function in GIS. This paper presents the problem of selecting 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 search strategy. In general, the goal of this study is to develop a (GIS) - based model to determine suitable route. Therefore, the required data for the proposed model building were identified by using, land use, transportation maps, aerial photographs and ographic features then reviewed for model development requirements. Four factors were considered; Geotechnical, Geometrical, social and economical factors for multicriteria evaluation to select the best route alternative. ARC GIS 9.2 software was used for the analysis and model building requirements. In actualizing the aim, satellite ages of the study area was provided while the land-use map was obtained fromDesign Office-Amanat Baghdad. The land-use over the study area was classified into eight different classes. A Digital Elevated Model (DEM) over the study area was downloaded from the Global Mapper Software, used to derive the slope map over the area of study and the Analytic Hierarchy Process (AHP) was used in weighting the ions. Finally, the case study demonstrated that GIS based on multi-criteria approach is recognized to be used as a tool for the optimum route selection by considering the factors affecting on the decision-maker route selection. Furthermore, saving of money, time and effort. | ||
