Nicholas Knize updated LUCENE-6908:
-----------------------------------
Description: The {{.testGeoRelations}} method doesn't exactly test the
behavior of GeoPoint*Query as its using the BKD split technique (instead of
quad cell division) to divide the space on each pass. For "large" distance
queries this can create a lot of irregular rectangles producing large radial
distortion error when using the cartesian approximation methods provided by
{{GeoUtils}}. This issue improves the accuracy of GeoUtils cartesian
approximation methods on irregular rectangles without having to cut over to an
expensive oblate geometry approach. (was: The {{.testGeoRelations}} method
doesn't exactly test the behavior of GeoPoint*Query as its using the BKD split
technique (instead of quad cell division) to divide the space on each pass. For
"large" distance queries this can create a lot of irregular rectangles
producing large radial distortion error when using the cartesian approximation
methods provided by {{GeoUtils}}. This issue will better divide the space
enabling use of the fast cartesian approximation methods instead of having to
convert to an expensive oblate geometry approach.)
