So we can't discuss things in previews. FYI, a lot of the map was "visible" in all the pictures of the CE and stuff released from R* with the blueprint and somebody put it together (damn close) from the GTAF.
I get it, you don't want to be spoiled. But it really isn't "that simple" since previews aren't "officially released by R*".
My question, if something as simple as a screen of the map you'll see before you even put the game in your system is considered a spoiler, why even be in the OT? It makes no sense ... unless you really just want to be "that guy".
