None of that information is even relevant to a pilot as there is no way to calculate or correlate the information to a chart without being a master at surveying, so should not even be listed. Are they saying a minima is infringed or take off distance reduced, a displaced threshold needed? That's what is important to me.... I know some airlines might use the info to calculate escape routes, however let that info go straight to the relevant parties. As a pilot I have no idea if they have accounted for x tree or not, I assume they have. I can read and see it infringes take-off surface gradients, but does that mean the STODA is wrong in ERSA?
