I have changes the formula to use vincenty's formulae. Slower as it is
iterative but It taken into account the planet model.
> New wrapper classes for Geo3d

> Key: LUCENE-7951
> URL: https://issues.apache.org/jira/browse/LUCENE-7951
> Project: Lucene - Core
> Issue Type: Improvement
> Components: modules/spatial-extras
> Reporter: Ignacio Vera
> Assignee: David Smiley
> Priority: Minor
> Attachments: LUCENE_7951_build.patch, LUCENE_7951_build.patch,

> Hi,
> After the latest developments in the Geo3d library, in particular:
> [https://issues.apache.org/jira/browse/LUCENE-7906] : Spatial relationships
> between GeoShapes
> [https://issues.apache.org/jira/browse/LUCENE-7936]: Serialization of
> GeoShapes.
> I propose a new set of wrapper classes which can be for example linked to
> Solr as they implement their own SpatialContextFactory. It provides the
> capability of indexing shapes with
> spherical geometry.
> Thanks!
