<font size="+1">Hi, does anyone know of a function or algorithm
which will help me in closing open multilinestrings (contours) (I
am using Postgis 2.0, Win 7 64).<br>
My contours are made up of several segments, all multilinestrings,
which sometime are closed but often are open at several places
along the same contour height.<br>
I can close them when the are open at the edge of the map by using
a section of the edge as the closing segment but the real problem
is when the contours are inside the map, e.g. when the several
segments making up the contour do not share common start or end
points but have a gap between them.<br>
Any suggestions would be most welcome.<br>
Thank you<br>
<br>
