title: Latitude/Longitude coordinates are not correct in amMap USA map
body: <p>I am building a map using the usaLow.js map. On map init, I call a json method that returns this data:</p>
  <pre><code>[{latitude: &quot;40.4258686&quot;,longitude: &quot;-86.9080655&quot;}]
  </code></pre>
  <p>With this data I add to the map's data provider (mapData) with this:</p>
  <pre><code>mapData.images = [];
  for(var i = 0; i &lt; resp.length; ++i){
    mapData.images.push({
      type: &quot;circle&quot;,
      color:&quot;#FF0000&quot;,
      latitude: parseFloat(resp[i].latitude),
      longitude: parseFloat(resp[i].longitude)
    });
  }
  map.validateData();
  </code></pre>
  <p>This location should be in Indiana, but this is where I see the marker: <a href="https://i.stack.imgur.com/vW1zZ.png" rel="noreferrer"><img src="https://i.stack.imgur.com/vW1zZ.png" alt="misplaced_marker" /></a></p>
  <p>Do lat/long coordinates need to be converted when not using world maps? If so, how can that be done?</p>
