According to ESRI

"To add a table of x,y coordinates to your map, the table must contain two fields: one for the x-coordinate and one for the y-coordinate. The values in the fields may represent any coordinate system and units such as latitude and longitude or meters."

I am getting confused here for example on GPS what is X,Y and are they different than Latitude,Longitude?

For coordinates captured using a GPS, or by any means, longitude is the X value and latitude is the Y value. These are for a geographic coordinate system and have units of degrees.

Alternatively your GPS may be set to return values for eastings and northings using a projected coordinate system with units often in meters (can be feet, etc).

  • Thanks PolyGeo so is this always through to say longitude is the X value and latitude is the Y ? doesn't matter is projected or not? and how about meter? – Mona Coder Nov 3 '17 at 20:58

    @MonaCoder Longitude will always be the X value and Latitude will always be the Y value. Projection doesn't matter, neither do the units. – Dan C Nov 3 '17 at 21:17
