> Key: LUCENE-6994
> URL: https://issues.apache.org/jira/browse/LUCENE-6994
> Project: Lucene - Core
> Issue Type: Bug
> Components: modules/spatial
> Reporter: Nicholas Knize
>
> This is a continuation of LUCENE-6908 which validates USGS accuracy of 0.5%
> for Sinnott haversine distance calculation. The issue also introduced a space
> segmentation approach for BKD distance queries near the poles. In LUCENE-6956
> a restriction on distance size was initially removed to randomly test BKD
> distance queries at any range. This revealed an issue where distance error
> nearly doubles for exotic rectangles created by BKD's split algorithm. This
> issue will investigate potential distance error caused by the segmentation
> approach introduced in the second part of LUCENE-6908.
