[mapserver-users] WMS Layer provided by MapSever rendering incorrectly in ol3.

[Michael Smith]

Neelesh,

You need to set your map projection to match your basemap. You need to set
it to spherical mercator.

 PROJECTION
    "init=epsg:3857"
  END

Subject:  [mapserver-users] WMS Layer provided by MapSever rendering
incorrectly in ol3.

> I have created a map using OpenLayers3 which contains two layers. First layer
> is Open Street Map Layer and the second one is WMS layer provided by the Map
> Server.
> Problem-When i'm rendering first layer it is rendering properly no issue. but
> when i'm rendering the second layer(provide by map server) it renders
> incorrectly means it does not fit to its container and it is out of sync with
> the first layer in terms of location. See this snapshot
> <http://i.stack.imgur.com/Ac8xR.png>  of the maps for more clarification. In
> the snapshot top layer is wms layer provided by map server.
>  <http://i.stack.imgur.com/Ac8xR.png>
> 
> 
> 
> Also when i'm zooming or moving the map then both layers work correctly but
> after a delay of few seconds the second layer(wms layer from map server) again
> switches back to its initial position(Position that is shown in above attached
> snapshot).
> 
> 
> This is the code that i'm using to consume wms service.
