title: Coordinate transform
body: <p>Do any open source or 'free' libraries exist for Java where i can perform coordinate transforms from one spatial system to another? </p>
  
  <p>I found Opengeo <a href="http://opengeo.org/" rel="nofollow noreferrer">http://opengeo.org/</a> but it's a huge and comprehensive library for all sorts of spatial things.</p>
  
  <p>Does anything smaller exist? I need to convert from MGA56 to WGS84.</p>
