title: How to convert an EPSG coordinate to a latitude / longitude?
body: <p>I have the following OpenGis data, which I want to convert to a latitude/longitude coordinate (as used by Google maps).</p>
  
  <pre><code>&lt;address xmlns:gml="http://www.opengis.net/gml"&gt;
    &lt;gml:Point srsName="urn:ogc:def:crs:EPSG::28992"&gt;
      &lt;gml:pos&gt;142629.0 523546.0&lt;/gml:pos&gt;
    &lt;/gml:Point&gt;
  &lt;/address&gt;
  </code></pre>
  
  <p>On the <a href="http://www.epsg-registry.org/" rel="nofollow noreferrer">EPSG Registry</a>, I found the origin position of EPSG:28992.</p>
  
  <pre><code>Latitude of natural origin      52°09'22.178"N
  Longitude of natural origin     5°23'15.5"E
  Scale factor at natural origin  0.9999079 unity
  False easting                   155000 metre
  False northing                  463000 metre
  </code></pre>
  
  <p>I've tried to using <a href="http://proj4js.org/" rel="nofollow noreferrer">proj4js</a>, but I can't figure out how to put this in a projection and how to get the required output.</p>
  
  <p>I've also tried calculating it myself. But I have no idea what I'm doing here and nothing really made sense :(.</p>
