[postgis-users] GEOS pointonsurface() threw an error!

[Ricardo Bayley]

Hi,

I am calculation the PointOnSurface for a table of polygons. I get this
error message


NOTICE:  TopologyException: found non-noded intersection between LINESTRING
(857703 1.04022e+006, 857648 1.04019e+006) and LINESTRING (857536
1.04019e+006, 857870 1.04019e+006) at 857648 1.04019e+006


ERROR:  GEOS pointonsurface() threw an error!

********** Error **********

ERROR: GEOS pointonsurface() threw an error!
Estado SQL:XX000

I checked the one of the rows that is getting this error with
ST_GeometryType and I get "ST_Multipolygon", although I dont get the
ST_AsText, or any output type.
Any ideas why ?


regards


Ricardo
