title: Projection issue with ESRI JSAPI and ArcGIS map service
body: <p>I was trying to obtain a gpx file with some coordinates by drawing on an Openlayers map with an ArcGIS baseMap.</p>
  
  <p>When I draw the polyline and create the gpx, if I open it on Google Earth, what I see is not what I drawed before, the line is totally different from the original and not positioned where I drawed it.
  I know it's a projection problem, I've tried trasforming the geometry object from Mercator to Geographic, also getting directly the geographic coordinates from the map coordinates, but nothing.
  I tried to set "spatialReference" to 4362 and then to 3857, but nothing changes.</p>
  
  <p>I'm going to use that .gpx on a gps device (the next week I'll go to the Svalbard islands and I need some gps tracks to go around Longyearbyen by snowmobile, there there aren't any sign of life out the town, so I must be prepared to it), when I'll be there I'll adjust the output right for the device they will rent to me, but now I need to save on the .gpx file almost the right coordinates.</p>
  
  <p>I'm getting from the map those coordinates:
  lat: 61.22582068741976
  lon: 4.684820015391338
  when I'm expecting instead something around 78. lat and 15. lon.</p>
  
  <p>This is some of the code I use to create the map (I'm not pasting the code I know it's not responsible of my problems):</p>
  
  <pre><code>    var initialExtent = new esri.geometry.Extent({"xmin":505615.5801124362,"ymin":8678955.717187276,"xmax":525935.6207525175,"ymax":8689168.654279819,"spatialReference":{"wkid":32633,"latestWkid":32633}});
  
      map = map = new esri.Map("map", {extent: initialExtent, logo : false});
      basemapURL = "http://geodata.npolar.no/ArcGIS/rest/services/inspire1/NP_TopoSvalbard_U33_CHL/MapServer/";
      map.addLayer(new esri.layers.ArcGISTiledMapServiceLayer(basemapURL));
  </code></pre>
  
  <p>Here I'm using wkid 32633 that is the default for that map, tried to change with known ones, but nothing happened.</p>
  
  <p>And now the code I use to get the coordinates:</p>
  
  <pre><code>        dojo.connect(tb, "onDrawEnd", getCoords);
          function getCoords(geo) {
              var r=confirm("Salvare tracciato?");
              if (r==true) {
                  geo = esri.geometry.webMercatorToGeographic(geo);   
                  for ( var path = 0; path &lt; geo.paths.length; path ++ ) {                   
                      for ( var pt = 0; pt &lt; geo.paths[path].length; pt++ ) {
                          tra += '&lt;wpt lat="'+geo.paths[path][pt][1]+'" lon="'+geo.paths[path][pt][0]+'"&gt;&lt;/wpt&gt;';
                      }   
                  }
              }
          }
  </code></pre>
  
  <p>"tra" is a variable that stores all the code I'll insert into the gpx file with an other function.
  The "webMercatorToGeographic" function transform the map coordinates to geographic ones.</p>
