What is a map scale
Map scales can usually be found on the outer edge of a map usually near the map s key a set of symbols that. Thus 1 1 000 000 is a smaller scale than 1 100 000.

As a representation of the world maps are compressed versions of the real world meaning that a large piece of land is recreated onto a smaller piece of paper or digital file.
The scale of a map is the ratio of a distance on the map to the corresponding distance on the ground. The scale of a map shows how much you would have to enlarge your map to get the actual size of the piece of land you are looking at. Map scale may be expressed as an equivalence usually by different units e g 1inch 1mile or 1 63 360. Sailing charts used.
Most maps carry linear or bar scales in one or more margins or in the title blocks. For example your map has a scale of 1 25 000 which means that every 1cm on the map represents 25 000 of those same units of measurement on the ground for example 25 000cm 250 metres. A map scale is a ratio of the distance on a map to the actual distance of the ground. Even as the map is enlarged or reduced in size the line has an.
Nautical charts are constructed on widely different scales and can be generally classified as follows. Or graphically as a bar scale. The scale statement can be accurate when the region mapped is small enough for the curvature of the earth to be neglected such as a city map. This simple concept is complicated by the curvature of the earth s surface which forces scale to vary across a map.
Map scale maps are a graphical representation of the world or a section of the world. The scale of a map is smaller than that of another map when its scale denominator is larger. Large scale maps make each feature look larger and show a smaller geographic area. Many maps are drawn to a scale expressed as a ratio such as 1 10 000 which means that 1 unit of measurement on the map corresponds to 10 000 of that same unit on the ground.
A graphic scale also known as the bar scale is a line that specifies the distance in kilometers or miles as they show on a map. Because of this variation the concept of scale becomes meaningful in two distinct ways. Ocean sailing charts are small scale charts 1 5 000 000 or smaller used for planning long voyages or marking the daily progress of a ship. A map scale is the relationship between a distance on a map and the corresponding distance on the earth.
Map scale is the ratio of distance of ground upon corresponding ratio on scale.
