Introduction
Given Iran's ongoing role in the Middle East and the constant threat of external threats, it is imperative that I take action on the critical and important steps of my country Of the measures that can prevent the occurrence of malignancies Choose the right place is the activity in which the ability of a particular region, the existence of appropriate and sufficient land and its consistency with other urban and rural land uses is analyzed to select suitable locations for the desired application. Among these, site appropriates selection analysis for Select critical, critical and important centers with effective conditions and factors in the selection is different from the analysis for trade and industry. In the process of appropriates selection some factors including the right location should take some factors including geomorphological parameters mission, type and size of the units and the natural features of the area must be considered. Since the initial studies to determine the suitable site Presidio as well as the construction expenses, it costs very huge and in terms of security it is very important. Thus, it requires using of appropriate methods in the process of site selection Presidio. Reducing costs and making the wrong decisions and increasing efficiency and performance in selecting critical centersA proper analysis can also prevent dissipation of funds and time. So to the importance of scientific research in site appropriates selection critical and sensitive geomorphologic assessment centers in Kermanshah province with 33 °, 40 'to 35 °, 18' N and 45 ° geographic location.
Methodology
In locating critical and sensitive centers using geomorphological parameters, this research has used questionnaire design through survey studies and interviews with geomorphological experts about factors affecting the selection of critical centers. Then ratings based on the weights of criteria for each factor was identified. Finally, data layers of region such as slope map, slope direction, elevation, line maps, distance from urban and rural centers, Distance from the river, fault maps, geological maps(1:100000) Climatic Parameters , Aerial photo with scale(1/55000) , Landsat satellite imagery ETM, TM, MMS and Google Earth are used to identify the landforms point addresses have been collected and converted into rasters and multiplied by the weights of the criteria, the suitable locations have been chosen. In this study, IRDAS IMAGING Software for image processing of satellite data, Expert Choice software for the analysis of hierarchical and weighted criteria, Arc GIS software for editing, layer preparation, analysis and final site selection and field studies for complying with the maps of the area and visits of existing military centers have been used to get final results
Results and Discussion
In this study, factors affecting the selection of critical and sensitive centers were prioritized and then appropriate weight for each parameter was considered. The overall rating for each factor has been obtained by multiplying the response of each rating in table valuation factors considering their coefficients. The sum has been calculated and by dividing the total points by the total number of questionnaires the final score has been revealed for each factor
Maps and base imagery have been collected and geo-referenced, sectioned in time scale and the layers required to form a thematic map have been prepared in vector format. Then all layers for comparison and involvement in decision making have been plugged in Raster Calculator from Spatial Analyst Tool. This give a raster of suitability for the area. The final map is classified into five categories including Very Good and Good (Dark Color), Medium (Half Tone) and Inappropriate Very Inappropriate (Light Colors).
Conclusion
In this research, the research tools are surveyed topographic maps, geology and satellite and aerial images of the area as well as interviews with experts identifying the effective factors in locating critical and important centers with emphasis on passive defense..And after identifying them using AHP (Multi Criteria Decision Making Models) in order to compare the criteria has been analyzed. Also according to the final map based on geomorphological factors in ARC- GIS software environment The area of optimum area for the location of critical and sensitive areas in the northern part is greater than the soothe In other words, Given the zoning we can saycan be said that Kermanshah province has more favorable and more favorable conditions in the north, northwest and south areas, and is in a more favorable condition, and the west and east areas have poor conditions.Today, using digital and elevation models and Earth science software can easily identify areas that have the most visibility and dominance around them.
