(*) Get GPS Location Button
When supported, clicking this button automatically fills in your current Latitude and Longitude within a few seconds.
When not supported, clicking the button does nothing.
The best accuracy (within about 10 meters) is obtained on devices with a built in GPS chip such as smart phones which can directly receive satellite GPS signals.
On computers without a GPS chip, Latitude and Longitude are guesstimated by Google based on your IP address and the known locations of the nearest WIFI access points and their addresses.
Check that the 'Get GPS' button works before you leave home.
If "get location" or "allow this webpage to access your location" are turned off in your smart phone's web browser, it can be difficult to turn back on.
You would probably like a desktop computer handy to lookup the instructions while you probe around in the browser setting on your phone.
