Support for serializing/deserializing geometry to geohash?

[JimBlaney]

I'm looking to see if implementing Geometry <-> Geohash functionality would be something that would be welcomed for inclusion in this library. I know there are other Java libraries to do Geohashing, but looking for something that explicitly constructs a java.com.esri.core.geometry.Geometry instance. Thanks!

@JimBlaney What types of geometry would you convert to and from geohash?

[JimBlaney]

My particular use case includes:

• point -> geohash
• geohash -> envelope
• geohash -> point (centroid)

[stolstov]

Preferably this should be a standalone Geohash class.
class Geohash:
static Envelope2D geohashToEnvelope(String geoHash) - envelope of the geohash cell.
static String toGeohash(Point2D pt, int characterLength) - converts a point to the geohash of given length. Other direction of conversion is to use geohashToEnvelope and get the envelope center.
static String containingGeohash(Envelope2D envelope) - longest geohash that contains the envelope
static String[] coveringGeohash(Envelope2D envelope) - up to four geohashes that completely cover given envelope.
