Interesting Geometry Over Sydney Australia - Ley Line Observations

A look at what appears to be a 3D depiction of a Pyramid covering a large area of Sydney. Defined by connecting four significant monuments, as well as a most significantly a node point on the Harbour Bridge. Now it must be said that there are multiple monuments, memorials etc. of all description all over Sydney, and I am sure that if you put your mind to it you could come up with all sorts of depictions of what ever takes your fancy.
So with that in mind I am not saying that this definitely is a pyramid laid out in a deliberate fashion ... However, the angles and distances may suggest otherwise, with the central diamond section all within tens of metres and less than1 deg. and the main section within a few metres and a degree or so. So when keeping it's size in my mind .. it is plausible.
I guess the question we must now ask is that when you consider the angles and distance and that this is a 2d depiction of a 3d model viewed from a certain perspective, could we extrapolate it's true proportions to see if they match any other particular pyramid that we may know of .. perhaps ..
