Hi:
I wonder what is the responsibility of projection in OL?
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.
The generated tiles cover 20 levels each have a resolution.
Now I want to add the layer to the map.
So I use this manner:
var lay=new OpenLayers.Layer.WMTS({
resolutions:[1.4,0.7........],
url:'',
......
tileOrigin:new OpenLayers.LonLat(-180,90)
});
map.addLayer(lay);
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.
Then I want to know what does the projectin do in OL?
