Subject [jira] [Commented] (LUCENE-3795) Replace spatial contrib module with LSP's spatial-lucene module
Date Fri, 17 Feb 2012 15:27:59 GMT


David Smiley commented on LUCENE-3795:

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

I look forward to working with you more Uwe.  It appears we do a lot of similar work -- geospatial
and trie stuff.

> 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:
 and the spatial-lucene module is intuitively in svn/trunk/spatial-lucene/.
