The basics
On a 1:25 000 map, such as an OS Explorer, one unit of length on the map represents 25,000 units on the ground. So 1cm on the map represents 25,000cm or 250 metres on the ground. On a 1:50 000 map, 1cm on the map represents 500 metres on the ground.
Besides, how much is 1 cm on a map?
A map scale might be given in a drawing (a graphic scale), but it usually is given as a fraction or a ratio-1/10,000 or 1:10,000. These “representative fraction” scales mean that one unit of measurement on the map 1 inch or 1 centimeter represents 10,000 of the same units on the ground.
Also question is, is a 1 24000 scale map bigger or smaller than a 1 100000 scale map? The 1:24,000 scale is fairly large. … They would be omitted, usually, from maps in the 1:50,000 to 1:100,000 scale range; these maps cover more area while retaining a reasonable level of detail.
In respect to this, what are the 3 types of scales on a map?
There are three main ways that scale is indicated on a map: graphic (or bar), verbal, and representative fraction (RF).
What does 1 100000 mean on a map?
The scale ratio 1:100,000 means that one unit of distance on the map represents 100,000 of the same units of distance on the Earth. So on a 1:100,000 scale map, one cm on the map equals one km on the ground because one km has 100,000 cm.
What does 1 250000 mean on a map?
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).
What does a 1 24000 map scale mean?
It is given as a ratio of inches on the map corresponding to inches, feet, or miles on the ground. For example, a map scale indicating a ratio of 1:24,000 (in/in), means that for every 1 inch on the map, 24,000 inches have been covered on the ground.
What does a 1 to 50000 scale map mean?
A graphical or bar scale. A map would also usually give its scale numerically (“1:50,000”, for instance, means that one cm on the map represents 50,000cm of real space, which is 500 meters) A bar scale with the nominal scale , expressed as both “1cm = 6km” and “1:600 000” (equivalent, because 6km = 600 000cm)
