Hi all.

Im not sure if you can help understand GPS and mapping system.
I have question on GPS coordinates. Perhaps this is basic question, however I wanted to clarify.

How accurate are google maps? I use a tool to retriever GPS coordinate from the following
Google Maps - Find GPS coordinates, longitude, latitude, altitude

The tools allows me to get a GPS coordinate for any given point. However what im not sure of is how accurate are these coordinate. Do you know how accurate these maps? Or is there a way to findout/calculate etc? If google maps weren’t accurate maps, do you know a map which I can use to get somewhat accurate coordinates?

Thanks
