Nicholas Knize updated LUCENE-6908: ----------------------------------- Attachment: LUCENE-6908.patch Patch includes: * update {{testGeoRelations}} to rewrite longitudinal span queries into 4 slices to reduce radial distortion error in {{GeoUtils}} cartesian approximation methods - this would be needed for BKD queries due to the nature of the split algorithm for large distance queries. * Incorporate distance error on {{isClosestPointOnRectWIthinRange}} for better approximation within BKD. * added comments and javadocs. > TestGeoUtils.testGeoRelations is buggy with irregular rectangles > ---------------------------------------------------------------- > > Key: LUCENE-6908 > URL: https://issues.apache.org/jira/browse/LUCENE-6908 > Project: Lucene - Core > Issue Type: Bug > Reporter: Nicholas Knize > Attachments: LUCENE-6908.patch > > > 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. -- 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
