@Beta public class GridCompression extends Object
Very early way of additional compression that can be applied to 2D double and byte arrays. This doesn't compress a
well as using
This class is marked Beta because it still has some improvement that can be done on it, like having more support for other array types.

LZSEncoding on a simply-serialized String produced by Converters.convertArrayDouble2D,
but you can use LZSEncoding on the results of this class to significantly reduce output size. Testing on a heat map
of byte values from -128 to 127 from a world map:
Base size : 1143142 // this is an uncompressed String produced by Converters LZS size : 89170 // this uses LZSEncoding alone on the above Base string Custom size : 216209 // this uses GridCompression alone Both size : 43120 // this uses GridCompression followed by LZSEncoding
This class is marked Beta because it still has some improvement that can be done on it, like having more support for other array types.
