What type of map scale is considered large?

A large map scale refers to a representation of the Earth's surface where the ratio indicates a smaller area is being depicted, allowing for greater detail. In this context, a scale of 1:75,000 and larger signifies that one unit measured on the map equates to 75,000 units on the ground or a smaller geographic area, which allows for more detail in features such as roads, buildings, and landforms.

This level of detail is beneficial for tasks requiring precise navigation or planning, such as military operations or urban planning. On a map with this scale, you can see features much more clearly than you would on a smaller scale map, which covers larger areas but offers less detail.

In contrast, scales of 1:1,000,000 and smaller or the range from 1:1,000,000 to 1:75,000 depict much larger areas where details become less discernible, focusing instead on broader trends and larger geographic features. Therefore, the answer accurately identifies large map scales as those that give a clearer and more detailed perspective of a specific area.
