Nicholas Knize updated LUCENE-6994: ----------------------------------- Component/s: modules/spatial > GeoUtils Distance accuracy degrades with irregular rectangles > ------------------------------------------------------------- > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
