Mobile: Geolocation Property (Project Property Setting)?

Does anyone know where the Geolocation data is found when it is selected under the Project Properties and what the use case is for it? My assumption was that it would return Lat/Long of mobile unit back through the client app for use by the Gateway, but I am not sure.

It exists in the tag browser.

Can you help me with the specifics as to where the Tag is in the Browser and what its name is perhaps?

Mine looks like it is hereā€¦

Thanks cmisztur2. I see where the data resides. However, I do not see data coming back from the device on these variables and I am not sure how you discriminate between multiple users data. If I had 10 users access the mobile app and I wanted to get their location information, how would I do that?
