<div dir="ltr"><div><div><div><div><div><div><div>Hi:<br><br></div>I wonder what is the responsibility of projection in OL?<br><br></div>Since I have our own map data which use the no-epsg:4326 projection, then we use the ESRI arcgis to generate the tiles and depoly them through the wmts service.<br>
<br></div><div>The generated tiles cover 20 levels each have a resolution.<br><br></div>Now I want to add the layer to the map.<br><br></div>So I use this manner:<br><br>var lay=new OpenLayers.Layer.WMTS({<br><br></div>
resolutions:[1.4,0.7........],<br>
</div> url:'',<br> ......<br></div> tileOrigin:new OpenLayers.LonLat(-180,90)<br><div><div><div>});<br><br></div><div>map.addLayer(lay);<br><br>It works. But as far as I know the default projection of the map is "EPSG:4326", while our layer is not. But it worked. Why? I have not make any projection translation.<br>
<br></div><div>Then I want to know what does the projectin do in OL?<br></div></div></div></div>
