I have made a start doing this in Sitrec, having erased a lot of the trees in Battery Park, but it's tricky as the Whitehall Building is largely hidden by scaffolding (?) on the 3D model. I also need to work out how to add the WTC towers - it seems less straightforward than just drawing a polygon as in Google Earth and then setting a height?With Sitrec, we can now use the Camera /"Fit Camera to Points" to nail down a camera location if there's sufficient perspective in the shot. This might be useful for some old cases like this.
You can use Sitrec's "Add Building". Right click on the ground, then move the handles to line it up. Dragging just outside a corner witll rotate.I also need to work out how to add the WTC towers - it seems less straightforward than just drawing a polygon as in Google Earth and then setting a height?
