[geos-devel] GEOSBuffer doesn't take all of my geometry

[Maximo Pech]

Hi, I'm having trouble with a geometry in WKT form, it begins like this:

POLYGON ((-97.3813520229492866 26.0028241269227607, -97.3813272725338663
26.0046293743595065, -97.3793295485156989 26.0046069937576725,
-97.3793543294448654 26.0028017481029394, -97.3813520229492866
26.0028241269227607), (-97.3813520229492866 26.0028241269227607,
-97.3813767710094567 26.0010188790133867, -97.3793791080158968
26.0009965019755249, -97.3773814473803014 26.0009740973626933,
-97.3753837891055838 26.0009516651750232, -97.3753589495133269
26.0027569077319392, -97.3753341075571370 26.00456214981606...

It's a polygon with many rings inside it. I'm trying to buffer it to make a
intersection operation with a lot of other geometries because GEOS says it
has a self-intersection at or near point -97.3814 26.0028, but after
buffering it my geometry becomes:

POLYGON ((-97.3813520229492866 26.0028241269227607, -97.3813272725338663
26.0046293743595065, -97.3793295485156989 26.0046069937576725,
-97.3793543294448654 26.0028017481029394, -97.3813520229492866
26.0028241269227607))

All of the remaining rings are gone.
