Understanding Eastings and Northings in Cartography and Surveying

Eastings and northings are coordinate systems used in cartography and surveying to locate points on a map or on the ground. They are used to define the position of a point in two dimensions, with the easting being the horizontal distance from the origin (usually the center of the map) and the northing being the vertical distance from the equator (usually the center of the map).

In other words, eastings represent the distance an object is located to the east of the center of the map, while northings represent the distance an object is located north of the equator. Together, they provide a unique set of coordinates that can be used to locate any point on the map.

For example, if a point has an easting of 100 meters and a northing of 200 meters, it means that the point is located 100 meters to the east of the center of the map and 200 meters north of the equator.
