Apologies in advance if this is the wrong forum for this. When solving Challenge 137 I noticed something strange about ST_Intersects. I created two fields after ST_Intersects didn't give me what I expected:
Thanks for trying @Qiu but this can't be the answer. The input in the formula is not two points.
I have put in a Line and a Polygon, not two points. The formula detects the intersection in some cases, but it is the inconsistency with the ST_Intersection function that is the issue. False results should line up with the Null results below, which they sometimes do but not every time.
