Coordinate transform

Question

Do any open source or 'free' libraries exist for Java where i can perform coordinate transforms from one spatial system to another?

I found Opengeo http://opengeo.org/ but it's a huge and comprehensive library for all sorts of spatial things.

Does anything smaller exist? I need to convert from MGA56 to WGS84.

Answer 1

There is a lightweight library written fully in Java.

Coordinate Transformation Suite (abridged CTS) is a library developed to perform coordinate transformations using well known geodetic algorithms and parameter sets.

CTS handles 4257 coordinate reference systems (3910 EPSG).

The source code of this project is located at:
