SegmentString::testInvariant(), Assertion `pts->size() leads to hangup.

[HowieBaldwin]

Hello everyone

 

I've been trying to import openstreetmap data in pbf format into postgis. However imposm hangs up in the middle of the process of inserting the data into the database. Do you have any ideas for how this can be solved?

 

Some specifications about the computer:

Ubuntu 10.04 LTS

Python 2.6.5

Imposm 2.4.0

PostgreSQL 8.4 / PostGIS 1.4.0

(A bit dated perhaps but I have no possibility of upgrading unfortunately.)

 

Here's the output from imposm:

Your GEOS version should be too old then. See the "Note" box here:
