Example
This example demonstrates how geo warping helps to consistently display multiple radar videos.
This figure shows the visual effects on the right side without geo warping that targets seen by two radars cannot be correctly displayed and it is unclear where the target is actually positioned. The red and yellow target echoes are seen be radars which are about 50 km away. The radars are also about 50 km away from each other. The semi-transparent pink color depicts the track history.
In this scenario even a radar projection is used but of course the radar projection center (COP) can be only at the position of one of the radars. Even larger inconsistencies can arise if a projection different from a radar projection is used. The geo warped view on the left side shows the consistently displayed radar echoes where both radar echoes are exactly at the real target's position.

Famous quotes containing the word example:
“Our intellect is not the most subtle, the most powerful, the most appropriate, instrument for revealing the truth. It is life that, little by little, example by example, permits us to see that what is most important to our heart, or to our mind, is learned not by reasoning but through other agencies. Then it is that the intellect, observing their superiority, abdicates its control to them upon reasoned grounds and agrees to become their collaborator and lackey.”
—Marcel Proust (1871–1922)
