Ladies and gentlemen; I'm trying to follow the Wiki example by Kevin Neufeld on overlaying tables.
I get all my linework from my two polygon tables into a third table just fine. When I get to the point of noding, up comes the following situation: dustin=# CREATE TABLE step2 AS dustin-# SELECT st_union(geom) AS geom dustin-# FROM step1; NOTICE: TopologyException: found non-noded intersection between 1.40568e+06 507103, 1.40568e+06 507100 and 1.40568e+06 507100, 1.40568e+06 507100 1.40568e+06 507100 ERROR: GEOS union() threw an error! dustin=# I find this greatly puzzling as I thought the whole point of this exercise was to put nodes into the linework... I must be missing something very simple! This is PostGIS 1.3.1 and GEOS 3.0.0.RC4 running against vanilla Ubuntu 7.04 PostgreSQL, I think 8.2.
