Which of the following is NOT a type of scale used on a map?

A geodetic scale is not recognized as a standard type of scale used on maps. In cartography, scales provide a means to represent the relationship between distances on a map and actual distances on the ground.

Bar scales, also known as graphic scales, are visual representations of scale on a map, allowing users to measure distances directly. Verbal scales express scale in words, such as "one inch equals one mile," providing an intuitive understanding of distance. Fractional scales use a ratio or fraction to denote scale, such as 1:50,000, meaning one unit on the map is equal to 50,000 of the same units in reality.

While geodetic concepts are important in mapping and understanding the Earth's shape and measurement, a geodetic scale is not a commonly used term in the context of map scales.
