Insurgency in Nigeria is becoming an order of day, especially in the north-east and the Niger-Delta due to the presence of Jamā'at Ahl as-Sunnah lid-Da'wah wa'l-Jihād or Boko-haram (meaning western education is forbidden) and militants such as the Niger Delta avengers (NDA) or Movement for the Emancipation of Niger Delta (MEND) respectively. Although the government is working hard to contain insurgency by sending military troupes to affected areas, there is still a lot to be done especially in the use of spatial terrain analysis for counter terrorism. Thus, this research has utilized the availability of satellite images to extract information of North-east terrain trafficability for strategizing by the military field commander. The analysis involves the use of land use/land cover classified satellite image, floodplain and floodability maps, digital elevation model (DEM), slope, soil information and hillshade images. All the shapefiles were converted into raster, re-scaled to 22m and indexed into five classes with the least trafficable areas having index 1 while the fastest trafficable areas were given an index of 5. The result of the conversions were inputted into the weighted overlay model which computes a trafficability suitability ratings represented by NO-GO, SLOW-GO, MODERATE-GO and GO areas according to their ability to allow movement respectively. The result showed 3.66% and 16.1% of the study area are NO-GO and SLOW-GO respectively with Local Government Areas (LGAs) at the extreme east (i.e. in and around Lake-chad) having the worst trafficability ratings (NO-GO and SLOW-GO) especially in the rainy season when the marshland/wetland is wet, and the flood-plain of Adamawa state when flooded either due to dam release from Lagdo dam of Cameroon or due to heavy rainfall, Maiduguri is also in this category because of the presence of obstacles such as built-up areas. Meanwhile 45.2% of the study area is MODERATE-GO due to Aeolian/desert soils while 35.0% of the study area has a GO rating because it does not hinder movement.
