What does scale mean on an OS map?
What does scale mean on an OS map?
Scale describes the ratio in size between something in the real world and its representation on a map. In other words, if a map has a scale of 1:50 000 then a distance of 1 cm on the map represents 50 000cm (500 m) in the real world.
What does a scale of 1 25000 mean?
A map scale correctly reduces the actual distance on the ground to a corresponding distance on a map. The first number is the unit on the map and the second number is the distance in real life of the same unit so 1: 25,000 means that 1cm on the map corresponds to 25,000 cm on the ground.
What does a scale of 1 1250 mean?
If a plan is at 1:1250, it means that a metre on the plan represents 1,250 metres on the ground. A centimetre on that plan would represent 12.5 metres on the ground. Smaller scales are possible, of course. For example, a double-page map of North America might appear at a scale of 1:15,000,000.
What does a 1 50000 map mean?
This gives the ratio of the map distance to the distance on the ground. This might sound complicated at first, but it simply means that with a scale of 1:50,000 one centimetre on the map represents 50,000 cm on the ground.
What does 1 1250 mean on a map?
Why is the scale important on a map?
To be most useful, a map must show locations and distances accurately on a sheet of paper of convenient size. The proportion chosen for a particular map is its scale. Large Is Small. Simply defined, scale is the relationship between distance on the map and distance on the ground.
What is scale and types of scale?
The Four Scales of Measurement. Data can be classified as being on one of four scales: nominal, ordinal, interval or ratio. Each level of measurement has some important properties that are useful to know. For example, only the ratio scale has meaningful zeros.
What does a map scale do?
Map Scale: Measuring Distance on a Map Words & Numbers Map Scale. A ratio or representative fraction (RF) indicates how many units on Earth’s surface are equal to one unit on the map. Caution. Graphic Scale. Large or Small Scale.
What does scale on a map mean?
The scale of a map is the ratio of a distance on the map to the corresponding distance on the ground. This simple concept is complicated by the curvature of the Earth ‘s surface, which forces scale to vary across a map.
What is a map scale?
Map scale refers to the relationship (or ratio) between distance on a map and the corresponding distance on the ground. For example, on a 1:100000 scale map, 1cm on the map equals 1km on the ground. Map scale is often confused or interpreted incorrectly, perhaps because the smaller the map scale, the larger the reference number and vice versa.
