followup questions about using Lunaserv with OpenLayers3

[Tamar Cohen]

Apologies, the last question posted when I pasted my example.

Any rate, I see that your example page is built in OpenLayers 2; I am working with OpenLayers3 and wondering if anyone has success using Lunaserv as the WMS server for OL3?

Specifically with a non-standard projection.

Thanks much for any input.

Tamar,

I've only played with OpenLayers 3 a little bit, but I had good luck
defining the IAU2000 projection using OL3's Proj4JS integration.
Basically you define it using the proj4 string and then you can use it
like any other projection.

You can define the projection using something like this:

proj4.defs('IAU2000:30120', '+proj=stere +lat_0=-90 +lon_0=0 +k=1 +x_0=0
+y_0=0 +a=1737400 +b=1737400 +units=m +no_defs');

Then the projection should be available to OL3. You can look up the
proj4 strings for IAU2000 projections at
http://spatialreference.org/ref/iau2000/

Thanks Nick -- the projection was no problem.  The issue I'm having is how to actually successfully retrieve data from the asu server.

Turns out I was using the wrong URL; this seems to work:

new ol.layer.Tile( {

        name: "asu_basemap",

extent: [-992800, -992800, 992800, 992800],

    source: new ol.source.TileWMS({url:'http://webmap.lroc.asu.edu/', //http://wms.lroc.asu.edu/lroc',

    params: {'projection': 'SP_STEREO', 

//     'c_lon': -14.192, 

//     'c_lat':-86.33,

    'c_lon': 0,

    'c_lat': 0,

    'x':0, 

    'y':0, 

    'resolution':3474.8,

    'srs':'IAU2000:30120',

    'version': '1.0.0',

    'LAYERS':'luna_wac_global'},

thanks!
