<h1 id="title">Using Proj4JS for vector reprojection</h1>
<div id="tags">

</div>
<p id="shortdesc">
The features are reprojected with the JavaScript library
<a href="http://proj4js.org/">Proj4JS</a>.
This example shows how to reproject vector features within
OpenLayers. The baselayer shows Germany in the projection
EPSG:31467 (GK 3). When one clicks on the buttons, features with
geometries originally in EPSG:4326 will be transformed to the
projection of the map on-the-fly.
</p>
<p>
The features are internally reprojected with the JavaScript library
<a href="http://proj4js.org/">Proj4JS</a>. Please note that usually
you would not inlude Proj4JS the way it is done in this example.
In a production environment you would furthermore have a local copy
of the Proj4JS-projection definition that is hotlinked in this
example.
