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
.
How do you read a 1 25000 map?
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.
How many cm would 1km be represented by on a 1 25000 scale map?
A map has a scale of 1:25000. This means that 1 cm on the map is
25000 cm
in real life, which is 250 m or 0.25 km. It is also useful to note that if 1 cm is 0.25 km, then 4 cm will represent 1 km in real life.
What is the scale of 1 25000 useful for?
Explorer maps are 1:25,000 (1 cm = 250 m). These are useful for
walking and other outdoor pursuits
. Landplan maps are 1:10,000 (1 cm = 100 m). These show individual streets clearly and might be used by town planners.
What does a map scale tell you?
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. … For example, a 1:100000 scale map is considered a larger scale than a 1:250000 scale map.
What does a 1 to 50000 scale map mean?
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)
How accurate is a 1 25000 map?
Map mark up, Measurements and Map Scales
If you mark up a feature such as a site boundary with a 1mm thickness line on a 1:10,000 map, then you will be accurate to +/-10
metres
, marking the same site on a 1:250,000 map will be accurate to +/- 250 metres.
What does a scale of 1 24000 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
. Ground distances on maps are usually given in feet or miles.
How big is a square on a 1 50000 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 read a physical map?
It shows: –
the height (elevation) of the land
; – the location of cities, borders, mountains; – the depth of the sea; – the location of rivers and lakes. You can also see lines of longitude and lines of latitude. Every map has got a title.
Where can I get 1 50000 maps?

What is largest scale OS map?
The main scales used by Ordnance Survey (OS) for surveying are
1:1250, 1:2500 and 1:10 000
. These are referred to as large scale maps, which is when features in the real world are portrayed larger on the map. OS also produce a number of mapping products at other scales, such as 1:25 000 scale and 1:50 000 scale.
What type of scale is 1 50 000?
1:50000 represents the map scale as a mathematical ratio or fraction, thus the name
ratio scale or fractional scale
. 1:50000 can be shown as 1/50000 as well. Here such a scale means that one unit of measurment on the map is equal to 50000 of the same unit on the ground.
What are the 3 types of scale?
- Fractional or Ratio Scale: A fractional scale map shows the fraction of an object or land feature on the map. …
- Linear Scale: A linear scale shows the distance between two or more prominent landmarks. …
- Verbal Scale: This type of scale use simple words to describe a prominent surface feature.
How is scale useful 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 map scale and types?
Types of Map Scales. We can relate map and ground with three different types of scale.
Verbal scale expresses in
words a relationship between a map distance and a ground distance. … The second type of scale is a graphic scale, or bar scale. This shows directly on the map the corresponding ground distance.
