|
How do you convert a grid azimuth to a magnetic azimuth?
|
By adding the G-M angle.
|
|
|
How do you convert a magnetic azimuth to a grid azimuth?
|
By subtracting the G-M angle.
|
|
|
Name the three (3) types of contour lines.
|

|
|
Under identifying specific terrain features, what does SOSES stand for?
|
Shape, Orientation, Size, Elevation, and Slope.
|
|
|
How do you orient a map to the ground by map terrain association?
|
Hold map in horizontal position. Line up features on the ground with those on the map. Place compass along one of the north-south grid lines to keep from orienting the map in the wrong direction (that is 180 degreees out), or by aligning two or more features. Incorporate the declination constant in determining the 30 degrees.
