Is easting and northing the same as longitude and latitude?

UTM zones in Europe. UTM coordinates are presented in the format longitude zone latitude zone easting northing, where easting is the projected distance from longitude zone's central meridian and northing is the projected distance from the equator. The values of both easting and northing are given in meters.

What is a grid survey?

A grid reference locates a unique square region on the map. Points can be located by grid references on maps that use a standard system for Eastings and Northings, such as the Universal Transverse Mercator used worldwide, or the Ordnance Survey National Grid used by Ordnance Survey in the UK.

How do Eastings and Northings work?

These grid lines help you to pinpoint an exact location anywhere on the map. The vertical lines are called 'eastings', as they increase in value as you travel east on the map. The horizontal lines are called 'northings' as they increase in value as you travel north on the map.

What is the purpose of a map grid?
