Hi, First I am not a Civil person, Now I have been given GPS numbers for some light pole locations and do not know how to locate using these numbers. Can they be converted to feet and inches? Do I need to be given a bench mark to work from?ThanksWayne

So what you have is latitude and longitude?Maybe this will help?
