Latitude Longitude unity

Hello.I’m totally new to programming and i’m trying to make an AR game for a school project.I need to know if i can place an object to a specific location (lat,lon) let’s say for example my city center.I saw many tutorials about the image target but i can’t find anything about the specific location.Any help?

Thanks in advance guys and sorry for the silly question i’m just totally new to this!

So are you placing objects on a sphere / globe or on a flat plane like a Terrain?
