Hello,<br>Is there a way to debug a problem I have with a polygon and line? I was running a query that used st_intersects and st_intersection to get the length of lines that are within the polygon. I was spot checking some of the data and came up with a particularly strange example.<br>
<br>Visually, the polygon looks as it should, the line clearly appears to be completely contained within the polygon however st_crosses returns true and intersection returns a subset of the line. I've tried this on postgis version 1.3 and 1.4 and both behave the same. I'm inclined to believe there is a stray point but given the polygon 2,700+ points I'm not sure how I find it! I suppose it's possible that there is a bug - or maybe I'm just completely missing something.<br>
<br>I tried finding the closest point on the polygon to the line - but when I tried to find a way to do this it seemed that the suggestions were for finding the closest point when the other point was outside the polygon?<br>
<br>Appreciate any help,<br><br>Thanks - Bryan.<br>
