What does it mean if the ratio of a map is 1 50000?

What does it mean if the ratio of a map is 1 50000?

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. We have an incomplete map and data coverage at 1:100000 and 1:50000 scales.

What size is a 1 50000 scale map?

Maths (still sorry): A 1:50,000 scale means that each millimetre on your map represents 50,000 millimetres or 50 metres on the ground. (Therefore 2 mm on the map represents 100 metres and 2 cm a kilometre).

How do you find the ratio of a map?

For the 1: 50 000 map, the scale is ‘2cm to 1 km’. My 12.8 cm is 6km plus just under half….Examples:

What is a ratio on a map?

The map scale is printed in the map legend. 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 type of scale is 1 50000?

Representative Fraction (RF) – Fractional Scale – Ratio Scale: 1:50000 represents the map scale as a mathematical ratio or fraction, thus the name ratio scale or fractional scale.

How accurate is a 1 25000 map?

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.

How do you calculate scale ratio?

To scale an object to a smaller size, you simply divide each dimension by the required scale factor. For example, if you would like to apply a scale factor of 1:6 and the length of the item is 60 cm, you simply divide 60 / 6 = 10 cm to get the new dimension.

What does 1 25000 on a map mean?

There is a standard ratio format for map scales e.g. “1: 25,000”. 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 1 cm on a map drawn at a scale of 1 50000 represent on the ground?

A scale of 1 : 50 000 is used on many Ordnance Survey maps. This means that 1 cm on the map represents an actual distance of 50 000 cm (or 500 m or 0.5 km).

What kind of scale is 1 40000?

Harvey map 1:40,000 scale (1cm = 40,000cm (400m) / 1mm = 40m / 2.5cm = 1km)

How many miles is 1cm on the map?

This means that 1cm on the map is 0.5km (or 500m which is 50,000cm) on the ground. In the UK, we tend to look at distances in miles and maps in inches. The following is a list of scales and their approximate ‘Miles to Inches’ conversions:

How do you work out the distance on the map?

To work out the distance on the map, we need to divide this length by 50000. 4.5 km = 4500 m = 450000 cm. Dividing 450000 cm by 50000 gives a distance on the map of 9 cm. Alternatively, we could have just remembered that each 0.5 km in real life is 1 cm on the map. If we divide 4.5 km by 0.5 km we get 9, so the distance on the map must be 9 cm.

What is the scale of a map?

The scale of a map is 1:50 000. What distance on the map wil by Mazen Ayman The scale of a map is 1:50 000. What distance on the map wil (b) Now imagine we want to walk 4.5 km in real life, and we need to find out how far this is on the map.

What is the value of 3 cm on the map?

This gives 3 cm × 50000 = 150000 cm which is 1500 m or 1.5 km. Alternatively, we could have just remembered that each 1 cm on the map is 0.5 km in real life. Hence, 3 cm on the map must be 3 × 0.5 km = 1.5 km in real life.
