> I'm opening this for discussion, because I'm not yet sure how to do
> this integration, because of my ignorance about spatial in general and
> spatial3d in particular :)
> Our BKD tree impl is very fast at doing lat/lon shape intersection
> (bbox, polygon, soon distance: LUCENE-6698) against previously indexed
> points.
> I think to integrate with spatial3d, we would first need to record
> lat/lon/z into doc values.  Somewhere I saw discussion about how we
> could stuff all 3 into a single long value with acceptable precision
> loss?  Or, we could use BinaryDocValues?  We need all 3 dims available
> to do the fast per-hit query time filtering.
> But, second: what do we index into the BKD tree?  Can we "just" index
> earth surface lat/lon, and then at query time is spatial3d able to
> give me an enclosing "surface lat/lon" bbox for a 3d shape?  Or
> ... must we index all 3 dimensions into the BKD tree (seems like this
> could be somewhat wasteful)?
