Hi Landon,
Data comes from external provider, I do not know which software they use for
creating the spikes. I am interested in getting rid of the spikes because a
certain browser application is sometimes snapping the spikes into dangling
segments which make real problem for us later.

What creates the spikes in your geometry?
I've got some code in JTS Warped that might help with this tool if anyone is
interested.

Hi,
QA option do find spikes (but not inside corner). Removing spikes is another
story. I had already to do that with JTS but it is a difficult problem because
you can't make sure that removing a spike will not create an invalid polygon
(auto-intersection).
Would be nice to have something in OpenJUMP though. I will check what I had
already done to see if it can find its way as a plugin.

Hey,
I couldn't find a standard tool either. So it would need to be via scripting.
Interestingly in QA theres is an option to check for min angle... so what you
want is the reverse. But I also don't know of a tool to fix that. Don't even
remeber if I implemented something alike in the mapgen toolbox, but it was
rather focused on buildings :/

Hi,
I would need a topology tool that could find and possibly remove spikes from
geometries. I believe that a spike could be defined as an angle of <-179
degrees or >179 degrees between two adjacent segments. Any suggestions?
