What is Small Scale Map and Large scale map ?

Small scale maps show large geographic areas, showing less detail. Large scale maps show small geographic areas, showing more detail. A maps scale will directly influence the size of the phenomena being represented on the map.

For example, a ground area of 300 x 300 meters square would be 4.80 x 4.80 millimeter square on a 1:62,500 scale map (small scale), while the same area would be represented as 12.80 x 12.80 millimeter square on a 1:24,000 scale map (medium scale). In, general, 'the larger the scale the more detail, the smaller the scale the less detail.
