Military Usage
In US military slang, "ground truth" is used to describe the reality of a tactical situation as opposed to what intelligence reports and mission plans assert the reality to be. The term is reflected in the title of the 2006 Iraq War documentary The Ground Truth and is used in military publications, for example Stars and Stripes saying "Stripes decided to figure out what the ground truth was in Iraq."
The military usage of the term is long-standing but its origins are obscure. It is plausible but difficult to prove that "ground truth" began life as military terminology and then was applied to other domains such as remote sensing control.

Famous quotes containing the words military and/or usage:
“There was somewhat military in his nature, not to be subdued, always manly and able, but rarely tender, as if he did not feel himself except in opposition. He wanted a fallacy to expose, a blunder to pillory, I may say required a little sense of victory, a roll of the drum, to call his powers into full exercise.”
—Ralph Waldo Emerson (1803–1882)
“Pythagoras, Locke, Socrates—but pages
Might be filled up, as vainly as before,
With the sad usage of all sorts of sages,
Who in his life-time, each was deemed a bore!
The loftiest minds outrun their tardy ages.”
—George Gordon Noel Byron (1788–1824)
