What does 1 25000 on a map mean?

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.

What does 1cm on a map with a scale 1 250000 mean

The is a representative fraction of a simple ratio of the map to the ground in the same units but the units are not written. This is a larger scale than 1 12000. 1: 250000 means that 1 cm on the map represents 250000 cm on the ground.

Which type of map is not accurate?

Though designed with the best of intentions — to provide a detailed and coherent projection of Earth — flat maps are far from accurate; some areas look far bigger than they really are, others appear much smaller, and distances between various land masses are misrepresented.

Which scale reads more accurate

Solution : The scale which is having th esmallest least count is more accurate.

Area Covered: A 1:25,000 map will cover a smaller area than a 1:50,000 map. This means that if you are doing a long walk, run or cycle you might need 2 or even 3 maps. This is when a mapping app like OS Maps, which allows you to plot and print just your planned route, can come in useful.

What does 1 20 000 mean on a map

This is the ratio between map and ground distance. It is written as either 1:x or 1/x, where 1 is the map distance and x is the ground distance in the same units of measurement. So a map scale of 1:100 000 means that 1 cm on the map is 100 000 cm on the ground AND 1 inch on the map is 100 000 inches on the ground.

What does a map scale of 1 to 24000 mean

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. Ground distances on maps are usually given in feet or miles.

What are the contour intervals on a 1 25000 map?

How do you calculate real world distance

  • Measure distance between two points on a map in cm or mm.
  • Multiply this by the scale of the map and divide by 100 000 if you used centimetres or by 1000 000 if you used millimetres to get kilometres.

What is more accurate than a map

Answer and Explanation: Globes are more accurate than maps for measuring the Earth because globes are a three-dimensional representation of the world, which itself is three-dimensional, while maps are flat, two-dimensional representations.
