--------------------------------------------
Note that there is something of a rework pending on contrib/spatial -- see http://lucene.markmail.org/message/4gaajqmhuxpwla7c -- maybe sync up w/ Chris to make sure this patch and his work fit together?

[jira] Updated: (LUCENE-1934) Rework (Float)LatLng implementation
and distance calculation
Posted by "Nicolas Helleringer (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/LUCENE-1934?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Nicolas Helleringer updated LUCENE-1934:
----------------------------------------
Attachment: LUCENE-1934.patch
Initial release of path :
- Removed loop for % use in longitude normalisation
- Recoded the Maths around distance calculation using well know implementation (ref: http://www.movable-type.co.uk/scripts/latlong.html)
- Changed UnitTest on doubles to use precision instead of exact comparaison (1e-4 of a mile precision)
- Introduced and spread the use of static initialized constants
May need some more work around class def and methods (used/not, static/not, etc ..)

---------------------------------------------
As Chris work is being released outside Lucene Apache project (http://www.jteam.nl/news/spatialsolr), should we consider this patch to be re evaluated to commit ?

Forgot :
- Removed local implementation of a degree to radian converter. Used Math.toRadians instead.

This has to be reworked when LUCENE-2359 and LUCENE-2366 will be closed to match code produced there.
