how to properly implement Open Transport Map

NigelAlford — Sat, 11 Dec 2021 22:51:19 GMT

I've worked through the example (which is broken) and can't seem to properly pull the Open Streetmap layers as a web tiled layer. In the example the server is returning back a 404 error, which leads me to believe that the service call or address has been updated by open transport maps.
This is the address given in the sample from Open Transport Maps

 http://[abc].tile2.opencyclemap.org/transport/${z}/${x}/${y}.png

Here's my non-working attempt:

 var sub = ["a","b","c"];
            var wtl = esri.layers.WebTiledLayer;
            var cycleMap = new wtl("http://{subDomains}.tile2.opencyclemap.org/transport/${z}/${x}/${y}.png",
            {
                "id": "OTranspoMap",
                "copyright": "OTM",
                "subDomains": sub
            });
map.addLayer(cycleMap);

I'm getting this error:

Uncaught TypeError: Cannot call method 'toString' of undefined

I've been searching around and haven't found anyone else with this question, but sorry if this is a repost.

In your format string try changing {subDomains} to {subDomain}.

http://${subDomain} (singular)

"subDomains":
in the JSON

 var cycleMap = new wtl("http://${subDomain}.tile2.opencyclemap.org/transport/${z}/${x}/${y}.png",
            {
                "id": "OTranspoMap",
                "copyright": "OTM",
                "subDomains": sub
            });

Is this a jquery function? if so I'll try adding the jquery library in the beginning

When I run the sample code, the tiles are not being found has anyone else seen this?

var cycleMap = new wtl("http://${subDomain}.tile.opencyclemap.org/cycle/${level}/${col}/${row}.jpg", {
          "copyright": "Open Cycle Map",
          "id": "Open Cycle Map",
          "subDomains": ["a", "b", "c"]
        });

I was able to get it to work: https://github.com/WSDOT-GIS/OsmTilesInArcGisJS.

It works fine, except it only has PNG tiles. change the url to png and it works.
