One often needs to know the distance between two points. Usually when this happens, it is possible to determine the distance by measuring it with a tape measure, ruler, or some similar device. But, to do this requires direct access to the points in question, i.e. you have to go to each point to make the necessary measurements.

Sometimes getting to a site is not possible, as for example when a point of interest is on the opposite side of a deep, impassable gorge. If this happens, one needs to invoke other methods of measurement - methods that do not require you to cross the gorge. This is where remote distance measurement comes in. Remote distance measurement, or "surveying", as it is usually termed, provides a means for measuring distance between points that may not be accessible.

There are no deep gorges to negotiate on the American Museum field trip, but you will be asked to measure the dimensions, e.g. foot length, of the Museum's tyrannosaur specimen. The specimen is protected by guard rails, so that you will not have direct access to it. You will not be able to lay a meter stick against the foot to measure foot length.
