Abstract
The defense force keeps the sovereignty of the nation and responsibility to the operation of mission
success at right time and place to control key terrain areas, to deliver logistics and to combat troops with
accurate terrain information. But manually combining terrain information is tiresome, time taking, costy
and results vary from expert to expert, therefore the analysis of terrain features for command post best site
selection is one of the basic tasks from different military operations and the study provides decision
makers and commanders to analyze the terrain visually using automated systems to obtain correct
information about the terrain and evaluate the terrain in terms of military aspects. To understand the
ground and achieve military goals, the basic sources of information for studying the terrain are
topographic maps, aerial photographs, military sketches and sand model. This research paper identifies
terrain features for defense command post site selection using RS and GIS techniques and customize and
publish maps in web-GIS C4I system for decision makers or commanders. The command post suitable site
selection is based on input data layers of elevation, slope, roads, land use land cover, soil types, geological
and geomorphological features. The multi-attribute and multi-criteria evaluation methods (GIS with AHP)
are used for factor analysis and aggregation. Multi factor analysis or weighted overlay analysis assigns
more importance of some criteria over the others. The AHP principle can be used to aggregate the priority
for all level of hierarchy structure and the method can be done using any GIS system having overlay
capabilities, combine input layers and generate the output command post suitable map. The result showed
that optimal sites clearly identified as a higher elevation weight equal to 39% influence is the most
important criteria from others. The resulting maps of GIS – AHP indicates best result and suitable location
for military command post in Ada’a district.
