title: What is the unit of getLength() method of com.vividsolutions.jts.geom.Geometry
body: <p>I am using Hibernate Spatial for developing a Web Application. I have MULTILINESTRING type Geometry and calculating length of the Geometry with geometry.getLength() in the following code snippet:</p>
  
  <pre><code>//Returns a Geometry object of MULTILINESTRING type.
  Geometry linegeom = routes.oltontShortestPath(oltlat,oltlong,ontlat,ontlong);
  double length = linegeom.getLength();
  </code></pre>
  
  <p>Now the question is what is the unit of "length"? How can I get the length in meter?</p>
