The 1:25 000 scale map is very useful for walking, but if you use it in a car you will quickly drive off the edge! On the other hand, maps at 1:250 000 scale (note the extra zero) show lots more area, but in far less detail. Maps are made at different scales for different purposes. To make it even easier, the grid lines are exactly 4cm apart, so every square is 1km by 1km. This means that every 4cm on a map = 1km in real life. Look at the front of a 1:25 000 scale map and you will see that the scale has been also written out for you like this: In fact it will also work with any vector layer, using the centroids of features that arent points, to caclulate the grid references. OS maps are divided into squares these allow you to find locations and features using grid references. It allows you to add British or Irish grid references, of any precision, to a point layer in QGIS. with data points were determined using the British Ordnance Survey National Grid. That might sound a bit complicated, but OS maps have been designed to make understanding scale easy. This tool was added to the FSC QGIS plugin with version 3.2. Map of England (shown in white) with 100 100 km grid squares of the. For example, if the scale on a map is 1:25 000, that 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). The scale of a map shows how much you would have to enlarge your map to get the actual size of the piece of land you are looking at. That's why some of our most popular maps, the OS Explorer and OS Landranger are often used for different activities - both have different map scales. The critical item that tells you how much detail is shown is called the 'scale'. Example: Here is a square kilometre at a 1:25,000 scale. This is when a mapping app like OS Maps, which allows you to plot and print just your planned route, can come in useful. This means that if you are doing a long walk, run or cycle you might need 2 or even 3 maps. Use a map with too little detail and it can be hard to use, while too detailed a map may mean you are continually going off the page or map sheet.
