Grant Ingersoll commented on LUCENE-2359: ----------------------------------------- So, you're saying then that your approach only ever has to retrieve 4 boxes no matter the radius? Do you have a reference URL to where we can read more about it? Also, please edit your table to reflect the error > CartesianPolyFilterBuilder doesn't handle edge case around the 180 meridian > --------------------------------------------------------------------------- > > Key: LUCENE-2359 > URL: https://issues.apache.org/jira/browse/LUCENE-2359 > Project: Lucene - Java > Issue Type: Bug > Components: contrib/spatial > Affects Versions: 2.9, 2.9.1, 2.9.2, 3.0, 3.0.1 > Reporter: Grant Ingersoll > Assignee: Grant Ingersoll > Priority: Minor > Attachments: LUCENE-2359.patch, LUCENE-2359.patch, LUCENE-2359.patch, > TEST-2359.patch > > > Test case: > Points all around the globe, plus two points at 0, 179.9 and 0,-179.9 (on > each side of the meridian). Then, do a Cartesian Tier filter on a point > right near those two. It will return all the points when it should just > return those two. > The flawed logic is in the else clause below: > {code} > if (longX2 != 0.0) { > //We are around the prime meridian > if (longX == 0.0) { > longX = longX2; > longY = 0.0; > shape = getShapeLoop(shape,ctp,latX,longX,latY,longY); > } else {//we are around the 180th longitude > longX = longX2; > longY = -180.0; > shape = getShapeLoop(shape,ctp,latY,longY,latX,longX); > } > {code} > Basically, the Y and X values are transposed. This currently says go from > longY (-180) all the way around to longX which is the lower left longitude > of the box formed. Instead, it should go from the lower left long to -180. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: java-dev-unsubscr...@lucene.apache.org For additional commands, e-mail: java-dev-h...@lucene.apache.org
