Nicholas Knize commented on LUCENE-6607:
----------------------------------------
Not sure I understand what you mean by automatically? Did you mean
deliberately? It was intended to provide a dependency free, lightweight,
GeoPointField type for the 90% use-case where people want simple geopoint
search using nothing other than the Core library. More advanced GIS'ish
capabilities? You'd bring on the spatial module, spatial4j, jts, ejml, sis,
etc. it's really that simple. Not sure what the problem is having a simple geo
API in core? Doesn't it just make core that much more applicable to different
application use cases? It's not a highlighter, not a suggester, it's a data
type. BKD is another simple type, but requires a different codec. I really
want to make both of these 3D capable. Unless I'm mistaken core is to have no
dependencies? If I'm wrong then this issue is moot anyway.

> Key: LUCENE-6607
> URL: https://issues.apache.org/jira/browse/LUCENE-6607
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Michael McCandless
> Assignee: Michael McCandless
> Fix For: 5.3, Trunk

>
> Geo3d is a powerful low-level geo API, recording places on the earth's
> surface in the index in three dimensions (as 3 separate numbers) and offering
> fast shape intersection/distance testing at search time.
> [~daddywri] originally contributed this in LUCENE-6196, and we put it in
> spatial module, but I think a more natural place for it, for now anyway, is
> Lucene's sandbox module: it's very new, its APIs/abstractions are very much
> in flux (and the higher standards for abstractions in the spatial module
> cause disagreements: LUCENE-6578), [~daddywri] and others could iterate
> faster on changes in sandbox, etc.
> This would also un-block issues like LUCENE-6480, allowing GeoPointField and
> BKD trees to also use geo3d.
