I like this idea. Normally I would try to avoid the use of words such as summarize that have different spellings in English and American, but we already have polygonize and use of function names of the form verb_noun such as generate_terrain, so we should stick with the proposed name.

Function needs a docstring of course.

This all looks good, just a single character addition requested!
