Sure, just one follow-up question: What will be the result of the fixed boost::geometry::remove_spikes( "MULTIPOLYGON(((4287 2160,5984 2160)))" )? Presumably "MULTIPOLYGON()"?

> B.T.W. I did not react on your last bug report, but it is noted and will be worked on, there are still some tickets open.

That's good to know, thank you very much!

Thanks again
