As discussed previously (see the devlist thread and the Jira), this proposal aims to add a first-class Geometry value type to Gremlin, following SQL/MM and PostGIS.

Each value carries a model, CARTESIAN or GEOGRAPHIC, backed by an SRID, which decides how it is measured. The proposal defines spatial predicates (geoWithin, geoContains, geoIntersects, geoDisjoint, geoWithinDistance, geoIntersectsBox, geoEquals) and steps (distance, buffer, envelope, asGeometry, asGeography), a Geometry(...) literal in the grammar, GType entries for the shapes and models, a total ordering, and a GraphBinary and GraphSON format.

JTS would become a new gremlin-core dependency.
