What type of map uses an alphanumeric grid?

Answer 1

An alphanumeric grid is one in which one axis' gradations are alphabetical, and the other, numeric. For example, a four-space alphanumeric grid would be described, from upper left, to right, then lower left, to right, as; A-1, A-2, B-1, B-2 A nine-space; A-1, A-2, A-3, B-1, B-2, B-3, C-1, C-2, C-3 C?...it's easy ;-)

Answer 2

Let's look at a situation with maps and make sure we're talking about the same thing.

Many maps are numbered along one side and have letters along the other. Thus the map is set up with an alphanumeric grid reference. Each letter and number allow the map to be subdivided into little "squares" or "boxes" by those characters. If the map is of a large area and we're looking for a town, should that town be given a letter and number reference, we simply look in the little box that is at the intersection of that letter and number. Instead of searching the whole map for a given town, we only have to look in a small box to find it.

By "carving up" a map with an alphanumeric grid and providing references, anyone using the reference list and the map can more quickly locate a given place. The ease of use is based on giving the map user a smaller area of the map to search for a given location. Rather than having to pick about across a whole map, an investigator can jump right to a small box and more quickly and efficiently locate a sought after location.

Answer 3

An alphanumeric grid is one in which one axis gradations are alphabetical and numerical. It represents latitude and longitude and helps determine absolute location.

Answer 4

A topographic map typically uses an alphanumeric grid to help locate specific points on the map by using letters and numbers to reference coordinates.
