Industrial site selection is an important point in the process of starting, expanding, or changing the location of industrial systems of all kinds. In a site selection process, the analyst strives to determine the optimum location that would satisfy the selection criteria. GIS and remote sensing technologies would provide a variety of options during the site selection process. The overall aim of the study is to identify suitable industrial site locations by using Geographic Information System and Remote Sensing based MCA-analysis. In order to conduct this study, a multi-criteria evaluation system to identify factors that influence site selection was considered. The results show the feasibility of GIS-based MCA as a useful approach for decision-makers to propose the best site selection. Furthermore, it is an effective tool for public administration to create the essential databases to perform spatial analysis. Interestingly, a suitability map is used in this study to identify the most suitable locations for the industry. This in turn investigated possible sites that were divided into four categories; unsuitable, suitable, moderately suitable, high suitability. The important factors that can affect industrial site were analyzed which includes topographic-slope, land use land cover, proximity to the main road, distance from a residential area. The findings of this study showed that land use and land cover factors were highly determined in the selection of industrial sites, and elevation and slope determine minimum compared with other factors. The majority of the study area was suitable and a small portion was less suitable.
