Grid references are a way to precisely pinpoint a location on a map by using intersecting lines on a grid. The vertical lines are numbered and are called eastings, while the horizontal lines are lettered and are called northings. The intersection of a specific easting and northing provides a unique reference point on the grid to locate a particular place.
expkain how four figure grid references are used to find places on map
Anything to do with coordinates.
Anything to do with coordinates.
It is that Longitude and Latitude are more accurate than alpha numetic grid references. :)
the combination of the numbers and letters are grid references. the squares are called the grid.
finding places on maps
Just use an internet search engine; it will bring up many references from grid vendors and researchers.
The disadvantages of four figure grid references are 1 grid reference is 10 2 is 10 3 is 30 and 4 goes to 400..
Grid references are used to pinpoint specific locations on a map. They consist of two sets of numbers or letters that provide a unique identifier for a position within a grid system, typically used in cartography. The horizontal line is the easting and the vertical line is the northing.
it means ......The Ordnance Survey National Grid reference system is a system of geographic grid references used in Great Britain, different from using latitude and longitude.
You should find the answer on the ordnance survey website: http://www.ordnancesurvey.co.uk/oswebsite/gi/nationalgrid/nghelp1.html In essence the first two digits of X and Y correspond to a grid of alphabetical references, giving you the first two letters of the BNG. Hope this helps.
A six figure grid reference is a more detailed type of grid reference. Basically you divide the squares into 100 smaller squares then write a three figure easting then a three figure northing all you really have to do is take away the decimal point
