Basemap Gallery Update Issues

StevenGraf1 — Mon, 22 Dec 2014 21:40:32 GMT

I noticed 3.12 came with some new basemaps.

1. Terrain with Labels draws on top of my layers I have added to the map.

2. If I switch to USGS National Map, it doesn't load. After a little bit of switching between maps, my layers disappear from my map entirely and can't turn them back on with checkbox.

Here is an older unsecured application this is happening on. I noticed on a version 3.8 AMD application I have it happens as well.

Anyone else experiencing the issue?

I suppose I need to update my apps to 3.12 release to get full support of the extra basemaps. Is there a way to specify which arcgis basemaps we want to show?

The USGS National map appears properly in the sample. As for your first question, is the problem that the labels are being drawn in front of your other layers? I noticed that happening in 3.11 also. This happens with the Oceans basemap too. Take a look at this example which shows the map's layers (including the basemap)

The USGS National Map doesn't work in my older applications.

For the first question, The labels, roads and water features seem to draw on top of my layers.

Yes, that happened in 3.11 and now in 3.12 (here‌).

I take it, it was designed that way?

I'm more worried about my layers disappearing and not being able to add them back in. It takes a little effort to make this happen in my v3.8 application. I will try and get it updated to 3.12 as soon as I can.

Thanks!

If it was designed that way, it's a mistake, in my eyes. The labels are one thing, but the line and polygon features shouldn't be placed on top of your features.

I'm not sure what you mean about your layers disappearing, though.

Ya, I would see it as a mistake also. I will try and reproduce the steps to make my layers disappear by switching basemaps and post back soon.

Thanks!

What's happening is the basemap gallery widget is timing itself out when it requests the USGS National Map. This causes all the layers that were in the map to disappear and I have to refresh the page to bring them back in.

Here is the error I am getting:

Mixed Content: The page at 'https://mysite.html' was loaded over HTTPS, but requested an insecure script 'http://basemap.nationalmap.gov/arcgis/rest/services/USGSTopo/MapServer?f=json&callback=dojo.io.script.jsonp_dojoIoScript2._jsonpCallback'. This request has been blocked; the content must be served over HTTPS.

The rest endpoint has an secured service but the basemap gallery is only pulling the unsecured service. Is there a way to fix this?

Thanks

I posted a similar issue (national map over https) and got NO responses. I'm mandated to use https for everything and I can't get that basemap to load either. Occasionally I'll run into a site that doesn't support https. That must be the case with the hosting server for that basemap.

If anyone knows of a workaround, I'd like to hear it too. Ideally that basemap would be changed to allow https connections.

you can use a proxy. That could be a work around

Adding a proxy and proxy rule took care of this issue for me. However, changing every map in my production environment just so one new basemap works isn't realistic.

This is how I have fixed this problem in the past. If you look at your browser's console you should see a CORS related error. This is why adding the proxy rule fixes the issue.

I took a look at the default maps in the Basemap Gallery and they are all available via https. Are you referring to National Geographic?
NatGeo_World_Map (MapServer)

https://server.arcgisonline.com/ArcGIS/rest/services/NatGeo_World_Map/MapServer/

If not can you provide more details about the basemap that is causing issues?

The USGS National Map loads over http. The rest work just fine.

This is the link it's trying to pull:

Thanks Steven,

I'll look into the National Maps issue.
