Here is an image of a angular map, that shows the major directions front (center circle), back (outer ring), ceiling, right, floor, and left (blue, red, green, violet resp.), left side of the illustration. You can overlay this on top of your angular environment map to roughly determine, which direction is where in your environment map. As long as the trees are mostly within the outer ring and the blue area is the sky it cannot be totally wrong (right side of illustration).
