What are map scales?
For a map to be of a useable size the information must be shown proportionately smaller than it actually is. This proportion is the “map scale”, which shows the relationship between distances on the map and distances in the ‘real world’. Map scales are usually given as a ratio, e.g. 1:100,000. In this scale, one unit of measurement on the map represents 100,000 of the same unit of measurement on the ground. The first number is always ‘1’ and the second number is different for each scale. “Large is small” or the larger the second number the smaller the scale (detail) of the map. Most geographical areas have been mapped at different scales. When choosing a map, its intended use should be considered before deciding on which scale to use. For a close view that will give you the most detailed information of a small geographical area, choose a map with a small second number, i.e. 1:100. For a broad general view of a large geographical area you would use a map with a larger second number, i.e
