> {{GeoPointField}} is a lightweight dependency-free postings based geo field
> currently in sandbox. It has evolved into a very fast lightweight geo option
> that heavily leverages the optimized performance of the postings structure.
> It was originally intended to graduate to core but this does not seem
> appropriate given the variety of "built on postings" term encoding options
> (e.g., see LUCENE-6930).
> Additionally, the {{Geo*Utils}} classes are dependency free lightweight
> relational approximation utilities used by both {{GeoPointField}} and the BKD
> based {{LatLonField}} and can also be applied to benefit the lucene-spatial
> module.
> These classes have been evolving and baking for some time and are at a
> maturity level qualifying for promotion from sandbox. This will allow support
> for experimental encoding methods with (minimal) backwards compatibility -
> something sandbox does not allow.
> Since GeoPoint classes are dependency free, all GeoPointField and support and
> utility classes currently in sandbox would be promoted to the spatial3d
> package. (possibly a separate issue to rename spatial3d to spatialcore or
> spatiallite?) Such that for basic lightweight Geo support one would only need
> a handful of lucene jars. By simply adding the lucene-spatial module and its
> dependency jars users can obtain more advanced geospatial support (heatmap
> facets, full shape relations, etc).
