메소드 설명
MakeSPT ( string>.IDictionary args, SpatialContext ctx ) : SpatialPrefixTree

The factory is looked up via "prefixTree" in args, expecting "geohash" or "quad".

The factory is looked up via "prefixTree" in args, expecting "geohash" or "quad". If its neither of these, then "geohash" is chosen for a geo context, otherwise "quad" is chosen.
