| Large Scale |
A map scale that covers a relatively small area on the ground and has a high level of detail. A small area of the earth's surface on one page is a large-scale map (i.e., a 1:500 map where 1 map unit equals 500 ground units is large scale compared with a 1:1,000,000 map). Contrast with small scale. |

| Scale |
It is the ratio of the distance measured on a map to that measured on the ground between the same two points. The larger the ratio, the smaller the scale. Therefore, a map of Dubai, would have a very small scale, whereas a map of a community within Dubai, will have a large scale. |
