Armed Forces

Military maps show the

Earth drawn to scale

as you would see it

from above

The military uses the

Universal Transverse

Mercator (UTM) and

the Universal Polar

Stereographic (UPS)

grid system.

Maps and Map reading are essential

skills that all of the armed forces

need in their occupation.

The military use grid maps in order to

find specific points on a map. They are

very useful in the military because they

can pinpoint specific places and the map

is also drawn to scale.

Polar projections show

the earth from one of

the two poles. Polar

projections show The

Great Circle Route.

Pilots use polar maps because it shows

the shortest path between two points.

The shortest distance can be found by stretching a string between them. The polar projections help air pilots go from point A to point B. The constant gyro track will be a great circle.

Pilots use pilotage. This is where

they use navigation with reference

to the visible features of the Earth.

The Importance of Map Projections in Different Professions

What map projections

do airline pilots use?

they don't need this)
