David Smiley commented on LUCENE-3795:
--------------------------------------
Uwe,
Thanks for bringing java.awt.geom.Area to my attention; I haven't noticed it
before. It looks workable, and the code for it looks impressive to me. As an
aside, JTS has a particularly scalable polygon scaling to many vertexes which
get stored in an in-memory RTree -- although I don't think this feature is as
pertinent for user-input polygons which would have a small number. It is
unfortunate that sun.awt.geom.Crossing is not exposed from Area, since
computing it is not particularly cheap and LSP will ask Area two things --
intersects() and contains() given a lat-lon box, and Area will compute the same
Crossing twice. Use of this in LSP would not be a "stategy", it would be a
subclass of SpatialContext which acts as a factory for shapes. Speaking of
which, I'm thinking of renaming the "simple" package to be something else like
"impl" since some of the implementations are decidedly not simple --
GeoCircleImpl case in point, and the addition of a polygon would seal that poin
t.
I look forward to working with you more Uwe. It appears we do a lot of similar
work -- geospatial and trie stuff.

> 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.
