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)
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 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).
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 scale of 1 25000 on an OS 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
.
Where can I get 1 50000 maps?

How big is a grid square on a 1 25000 map?
All OS maps are criss-crossed by vertical and horizontal grid lines (coloured blue on OS Explorer maps) which are
4cm apart on 1:25,000 scale maps
and 2cm apart on the 1:50,000 scale. A grid reference uses six figures to identify a particular spot on a map that is 100 metres square.
What are the two types of scales?
There are two main types of measurement scales, namely;
comparative scales and non-comparative scales
.
How do you calculate scale?
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.
How do you convert inches to miles on a map?
If the scale were
1:63,360
, for instance, then 1 inch on the map would represent 63,360 inches or 1 mile on the ground (63,360 inches divided by 12 inches = 5,280 feet or 1 mile). The first number (map distance) is always 1.
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.
Why would a town planner use a map at the 1 24000?
Why would a town planner use a map at the 1:24,000 scale rather than a map at the 1:250,000 scale? The map at the 1:24,000 scale
shows a much larger area
. The map at the 1:24,000 scale is easily converted to non-metric measurements. … The map at the 1:250,000 scale shows the town in too much detail.
What is an example of a large scale 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 is the meaning of 1 50000?
a representative fraction to describe the ratio between the map and the real world. This can be shown as 1:50,000 or 1/50,000. … This means that
