Brent,

OGR reroutes GEOS errors and warnings via the CPL error reporting
mechanism.  So, if you are working programatically you could
install a custom warning/error handler (see CPLPushErrorHandler()
for instance).

If you are just using the utilities there is no practical way to filter
out the GEOS messages other than by redirecting stderr to
/dev/null.

Best regards,
