What do the 'e' and 'n' suffixes in coordinate notation indicate?

• A. Easting and Northing
• B. Latitude and Longitude
• C. Elevation and Northing
• D. Time and Date

Answer: (A)

The suffixes indicate the two axes used in a grid-based coordinate system. The easting is the distance eastward from the grid’s origin along the horizontal axis, typically measured in meters, while the northing is the distance northward from the origin along the vertical axis. Together, they pin down a precise location on a map, as seen in systems like UTM. Latitude and longitude, by contrast, are angular measurements in degrees, not linear distances, so they don’t use easting and northing. For example, a point with easting and northing values specifies exactly how far east and how far north it sits within a given zone, making the location unambiguous on a planar map. Therefore, the e and n suffixes denote Easting and Northing.
