Your longitude and Latitude values are needed by our google maps addon to determine your exact location. You will need these values when submitting a standard listing.
To get these values for your address, just do a google search for your locations's latitude and longitude. Your longitude will have a negative value.
Alternatively, open google maps, type in your address in the search bar, or navigate to your address on the map. Click and hold your location for a few seconds and release your mouse or finger.
Your latitude and longitude will pop up, separated by a comma.
