Subject [jira] Updated: (LUCENE-2139) Cleanup and Improvement of Spatial Contrib
Date Wed, 09 Dec 2009 15:33:18 GMT


Chris Male updated LUCENE-2139:

    Attachment: LUCENE-2139.patch

Added patch.

Couple of TODOs still noted in the patch related to distances.  We need to decide what distances
we are going to use for the radius and circumference of the Earth and then use them in SpatialConstants.
 Currently the SpatialConstants values are taken from Wikipedia and other sites, yet differ
from some of the distances in the coded.

Also the patch doesn't seem to remove a couple of empty packages.  Too many changes in 1 patch
confusing the IDE I think.  Help cleaning this up would be appreciated.

> The current spatial contrib can be improved by adding documentation, tests, removing
unused classes and code, repackaging the classes and improving the performance of the distance
filtering.  The latter will incorporate the multi-threaded functionality introduced in LUCENE-1732.
> Other improvements involve adding better support for different distance units, different
distance calculators and different data formats (whether it be lat/long fields, geohashes,
or something else in the future).
> Patch to be added soon.
