David Smiley commented on LUCENE-6578:
--------------------------------------
FYI I posted to ReviewBoard so that my edits can be seen clearly:
https://reviews.apache.org/r/36035/
One observation I had, perhaps not introduced in this issue, is that
GeoPoint.magnitude() should always be 1.0 when using the sphere planet model
yet the GeoPoint itself doesn't "know" that. So it goes and computes the
Math.sqrt and it's cached. I'm not sure if it's worthwhile, in some issue
other than this of course, exploring if GeoPoint should have a unit-sphere
subclass different from the non-unit sphere subclass. Just a thought.

> I've got an application that seems like it may need the ability to compute a
> new kind of arc distance, from a GeoPoint to the nearest edge/point of a
> GeoShape. Adding this method to the interface, and corresponding
> implementations, would increase the utility of the package for ranking
> purposes.
