What is terrain analysis in military?
Military terrain analysis is ‘the collection, analysis, evaluation, and interpretation of geographic information on the natural and man-made features of the terrain, combined with other relevant factors, to predict the effect of the terrain on military operations’ (DoD, 2010).
What are the five military aspects of terrain?
(2) The terrain is analyzed in terms of its five military aspects which can be remembered easily by using the acronym “OCOKA.” This stands for “observation and fields of fire, cover and concealment, obstacles, key terrain, and avenues of approach.” These must be analyzed in light of the mission of the unit, the type …

What is terrain analysis ROTC?
Define terrain analysis. The collection of geographic information on natural and man made features to predict the effect on military operations. Purpose of terrain analysis. Success of operation depends on leader’s understanding of how weather and light will effect his soldiers and the enemy.
What three things must leaders consider when analyzing terrain army?
What is decisive terrain army?
Decisive terrain is key terrain whose seizure and retention is mandatory for successful mission accomplishment (FM 3-90). Decisive terrain is relatively rare; it is not necessarily present in every situation. Unlike key terrain, decisive terrain is not associated with any COA.
How do you create a Dem?
Create a digital elevation model (DEM) from the contour layer.
- Navigate to System Toolboxes > Spatial Analyst Tools > Interpolation > Topo to Raster.
- Select the contour layer as the input feature data.
- Specify the location of the output surface raster.
- Set the output extent the same as the contour layer’s extent.
What are the terrain mapping techniques?
Terrain mapping techniques include contouring, vertical profiling, hill shading, hypsometric tinting, and perspective view. A contour line map. The contour line of 900 connects points that are interpolated to have the value of 900 along the triangle edges.

What is key terrain?
In military doctrine, key terrain refers to areas which, if seized, afford an advantage to an attacker or defender.

What is key and decisive terrain?
Key or Decisive Terrain Some terrain feature (natural or manmade) which, if controlled, will give a marked advantage to whoever controls it. Often selected for use as battle positions or objectives. Echelon of command, mission, enemy, and situation dependent.
What are the types of DEM?
There are two types of DEMs – Digital Terrain Models (DTMs) and Digital Surface Models (DSMs).
What is DEM and TIN?
A DEM represents a regular array of elevation points. It can be converted to an elevation raster by placing each elevation point at the center of a cell. ● A TIN approximates the land surface with a series of nonoverlapping triangles.
