#626 closed defect (fixed)

Intersection with result from intersection --> TopologyException Error

Reported by: rajanski Owned by: geos-devel@…
Priority: major Milestone: 3.3.9
Component: Default Version: 3.3.8
Severity: Significant Keywords: intersection, st_intersection, topology exception
Cc: geosbug@…

Description

I have three geometries (Attached).

I am intersecting the first two,and then intersect the result with the third geometry.

Follows the error message

Error performing intersection: TopologyException?: found non-noded intersection between LINESTRING (15.1068 51.0102, 15.0974 51.0034) and LINESTRING (15.1068 51.0102, 15.0976 51.0036) at 15.101547860470001 51.006448703862588

but only when Iam directly taking the geometries from a table (see attachment)

When I produce the geometries with st_geomfromtext, it works.

When I take the geometries from the table, transform themto text,and then back to geometry,it also works.

Hi all, we need this problem solved (i.e. GEOS debugged) for a large project over here.

There is a budget and we invite devs to make offers.

We are located in Berlin, Germany.

Kind regards
