proj4leaflet not working?

swillmes commented 6 years ago

Hi there,

it looks like I don't get this simple task solved for whatever reason...

The objective is to just define a polarstereo projection (EPSG:3413) and have a WMS displayed in the Leaflet map with this CRS. I had it working with openlayers, but I do not succeed in Leaflet. Anyone an idea what the issue could be ... ?

    var crs3413 = new L.Proj.CRS('EPSG:3413',
        '+proj=stere +lat_0=90 +lat_ts=70 +lon_0=-45 +k=1 +x_0=0 +y_0=0 +datum=WGS84 +units=m +no_defs'
    );

    var map = L.map('map', {
            crs: crs3413
    });

    var wmsLayer = L.tileLayer.wms('http://www.gebco.net/data_and_products/gebco_web_services/web_map_service/mapserv?', {
        layers: 'GEBCO_LATEST',
        version: '1.1.1',
        format: 'image/png',
        attribution: 'myattribution'
    });

    wmsLayer.addTo(map);

    map.setView([90,0], 2);

Thx ...

There are some previous issues regarding problems with polar stereo projections, maybe you are facing a similar issue to them? Check out #42, #82, #102, #112, #149.

I'm going to close this - I think @pthorin's suggestions sum it up.

If you believe this is another issue than the linked above, please:

provide a description of what problem you're actually seeing (it's not clear to me after reading the comment above)
set up an example illustrating the problem on for example jsfiddle or codepen

Not trying to be complicated, but please realize that the time available for maintaining this project is small, and although unfortunate, issues without a clear description or that requires time for us to even understand the problem is likely to be left untouched.
