David Smiley commented on LUCENE-3795:
--------------------------------------
LSP is comprised of several modules:
* spatial-lucene: The heart of the project.
* spatial-solr: Solr support, notably field types using spatial-lucene.
* spatial-extras: An extension of spatial-lucene that uses JTS (LGPL licensed)
for polygon support.
* spatial-demo: A demonstration web UI using OpenLayers, Solr, Wicket, and the
other LSP modules.
The spatial-solr module of LSP can be considered in another issue following the
conclusion of this one. The other modules aren't being considered for
incorporation into Lucene/Solr.
LSP is largely new code although some of it originated using chunks of the
existing Lucene spatial contrib module and SOLR-2155 (A recursive
PrefixTree/Trie algorithm using geohashes). It's fair to say this is a
superset and descendent of SOLR-2155 but with a real framework around it and
plenty of refactorings and tests.
I ran Atlassian's Clover code coverage to get some statistics of this
spatial-lucene module of LSP:
* LOC: 6,605, NCLOC: 3,959
* Packages: 18, Classes: 70
* Code coverage: 53%
The code coverage surprises me a little... perhaps the number is higher when
the spatial-solr module gets involved which uses more of the classes then the
tests do here alone.
> Replace spatial contrib module with LSP's spatial-lucene module

>
> Key: LUCENE-3795
> URL: https://issues.apache.org/jira/browse/LUCENE-3795
> Project: Lucene - Java
> Issue Type: New Feature
> Components: modules/spatial
> Reporter: David Smiley
> Assignee: David Smiley
> Fix For: 4.0
>
>
> I propose that Lucene's spatial contrib module be replaced with the
> spatial-lucene module within Lucene Spatial Playground (LSP). LSP has been
> in development for approximately 1 year by David Smiley, Ryan McKinley, and
> Chris Male and we feel it is ready. LSP is here:
> http://code.google.com/p/lucene-spatial-playground/ and the spatial-lucene
> module is intuitively in svn/trunk/spatial-lucene/.
> I'll add more comments to prevent the issue description from being too long.
