Task

As GIS specialists, we are tasked by the commanding officer with the establishing deployment site(s) of a signal tower(s) that will act as a relay station in order to establish communication with the platoon. The signal mask has a frequency coverage of 12 km, when erected is 5 meters in height. In the accordance with the military doctrine, the signal towers must not be deployed with 2 kilometres of any residential areas or industrial areas. Develop a suitable model to identify the possible deployment and erection site(s) of the signal tower.

Conclusion

Based on the results of the spatial analysis used, between St. Helena bay and the HQ ( 4 Special Forces Regiment). There are several points that have higher elevation for the mast however some were not visible from the viewpoint of choice. A Spatial analyst tool was used to test for visibility and non-visibility. This tool among the other tools that were used, enabled us to identify the Possible deployment position. The criteria for such selection was mainly based  on viewshed and elevation.
