we are right now investigating an issue when simplifying geometries with GDAL, which seems to be caused by https://trac.osgeo.org/geos/ticket/741 in GEOS. The respective fix made it to GEOS 3.6. We are investigating into options for pulling GEOS with the fix included into our builds. Do you have plans to update GEOS to 3.6 (we are happy to use unstable or backports)? If not, do you think it's feasible to cherry-pick the fix into the current package?
As reported on this list, updating the geos package to 3.6/3.7 is blocked by OSSIM. [0]
The OSSIM 2.2.0 release has support for the newer GEOS, but has other issues that prevent its inclusion in Debian. [1]
Development of the OSSIM project is less than ideal, being driven by funding instead of community needs. So it's unclear when the remaining issues will be resolved.
If this takes too much time, I'll ask the OTB project to drop their OSSIM dependency so we can remove OSSIM from Debian to unblock the GEOS upgrades.
Cherry-picking the fix into the geos package may be possible, but I'll need to investigate this further. Ideally upstream releases GEOS 3.5.2 which that fix included.
