Encoding polyline algorithms in java

The following algorithm is used with Google Maps: http://code.google.com/intl/ru-RU/apis/maps/docume开发者_开发技巧ntation/utilities/polylinealgorithm.html

Are there any alternatives? The purpose is to encode geodetic polylines for transfer from server to a client.

In the case of Google's approach, what is the best implementation in java?

I found this site: Encoding polylines for Google Maps.

It implements Google Maps API polygon and polyline algorithm in Java and other languages.

Don't know if it could be useful to you.
