@Roxanne, thanks for your interest in my problem, sorry that I didn't explain better. When you draw polygon layers with dashed or dotted line styles they can look very bad because lines from adjacent polygons are drawn over top of each other and the symbols (dots, dashes, etc.) do not align. So I just want all the unique linestrings so that they will only be drawn once. I want linestrings, not just individual segments, for cartographic appearance and for performance. And since it's just for cartography, I don't care about attributes, line direction, or topology.
Aah.. Thanks for the illumination. As I said - a lot of people - a lot more knowledgeable... I am glad you found an answer.
Happy plotting... Roxanne _______________________________________________ postgis-users mailing list [email protected] http://lists.osgeo.org/cgi-bin/mailman/listinfo/postgis-users
