How to add this layer?

Hi, I would like to add USDA 4 band false color IR WMS map layer to Cal Topo, but I don't understand how to do it.

This explains the data:

I think this is the data:

This is what that data looks like hosted by ESRI, but I want to put this NC data into my own CalTopo map.

    Generally, you would want to do Add New Layer -> Add Custom Source and into the auto-configure URL textbox on the right side of the dialog, paste either the mapserver or wms endpoint:

    However that server seems dog slow at the moment so I'm not able to test it out.

    CalTopo has an NAIP false-color IR layer built in, although it doesn't have 2016 data yet.

    Thanks for the instructions. I'm making progress, but still not there yet.
    I add "Add New Layer" in lower left corner
    then "Add Custom Source"
    then I paste the URL in the "Auto Configure URL" box and hit "Go"
    then in the "Custom Map Source" pop-up window I choose "NC 1M 4B 2016"
    When I hit save it says "Server does not appear to support a compatible projection. Will try anyway, but this will probably not work". I say OK to that and try to continue.
    Then I click Save on the "Custom Map Source" box.
    All I can see is the grid boxes of where the imagery would be.

    Yeah, the default CalTopo layer is really nice, but the USDA 2016 one has better contrast, sharper color in the area I'm looking at.

    The server is working for me now - it looks like it only provides coverage footprints, not the actual imagery. Open the first URL I pasted directly in a browser and it will show the layers as a hierarchical tree. All the parent folders include "coverage" in the name, which generally means that the layer only shows you the coverage footprint of the actual source data.

    The imagery on the page is coming from an ArcGIS server (, not a government-run server. Beyond any licensing issues, it I looks like my server can't parse that URL.

    Hey, I'm trying with this map service (link below), but the 'GO' button doesn't appear to do anything. I'm guessing I have a projection problem, but if there is a way to display the layer, it gives great resolution for an area that is important for my work. Thanks!

    I'm going to kick this over to one of our developers Matt. The short answer is that this isn't a WMS or WMTS server it's an image server which is why it's not auto configuring off the URL. That said there's still a way to get it to work, that doesn't seem to be right now.

    I remember looking into this, I thought it was responded to - sorry that doesn't appear to be the case. The auto-configure URL doesn't work with imageserver URLs. Try this:
