Basemap Widget in new Experience Builder displaying current map

DeirdreSmyth — Fri, 23 Jun 2023 11:13:09 GMT

Hi There,

I am using the new basemap widget that became available in the latest release. I have an experience builder site that uses a webmap for the main map with a overlying feature layer and a basemap.

I've selected a subset of basemaps that I wish to use from my organizational basemap gallery but the issue is the widget is displaying the selected basemaps and also the main webmap as an option in the basemap list. The main webmap within the widget shows as a thumbnail of the overlying layer but it is labelled as the basemap which is confusing and incorrect!

I have not specifically added the main map to the basemaps list it seems to add it in itself, is there a way to remove it, or rename it so it at least has the correct name?

Dee

@DeirdreSmyth , thanks for letting us know. We will take a look.

@DeirdreSmyth This is the designed behavior of the Basemap Gallery widget, to allow users to switch back to the original basemap if needed. There is no way to remove it.

However, if you want to rename it, I believe it can be modified in the org/group basemap settings if you are using a designated one.

@TonghuiMing, I understand the need to allow users to switch back to the original basemap of the map but the thumbnail is that of the overlying layer so it is incorrect in the basemap widget:

Here I've switched off the overlying layer, you can see the basemap is called Standard Basemap and it is displayed in the main map. In the basemap widget the Standard Basemap thumbnail is that of the overlying layer and not the Standard basemap.

@DeirdreSmyth I believe what you have come across is this case - when the basemap itself does not contain a thumbnail, we will retrieve a substitute from the map widget, which I believe when created has the overlaying layer.

The basemap has a thumbnail @TonghuiMing, I've added the main map basemap to the app separately and it has the correct thumbnail.

If would be useful to be able to exclude this and not have it added by default if at all possible.

I see. We will keep a note of this and evaluate the enhancement possibilities. Thanks for bringing this up.

I believe I'm experiencing a similar issue - when I use the Basemap picker included in the Map widget, there is a duplicate basemap listed for the default basemap I am using for the app web map. (We have a custom Basemap group for our organization that we're using for the basemaps.) The issue is avoidable in the standalone Basemap widget by unchecking the basemap in question so that it only appears once. However, it would be nice to be able to use the basemap picker in the Map widget and not experience this issue.

That reasoning is completely unnecessary. The Basemap is in the gallery already. It just confuses the user by having two of the same base maps. Furthermore, the duplicate basemap has a different thumbnail further making the user think it is a different basemap. The developers overthought this one. The workaround is the basemap picker - thank you @WorcesterGTSS but it shouldn't be necessary plus I don't get to use the preferred thumbnail. At the very least, make the duplicate basemap an optional item.

Yip - got the same issue - happening in the basemap picker in the map and in the basemap widget. It if showed the correct thumbnail and not an image of my actual web map it would be fine. As it is it's confusing for the user and annoying for me.

P.S It doesn't work like this anywhere else that I have seen. For example - instant apps are fine.

The one with the image of my web map is not even an option when I go to choose which basemaps I want. It just turns up in the widget.

This is the expected. Other than the custom ones chosen, the current active basemap will be added to the 1st of the runtime list.

@WorcesterGTSS In your screenshot, the two basemaps should be different even though they look alike by the thumbnail. They don't share the same label either as I checked.

Re: Basemap Widget in new Experience Builder displaying current map

WorcesterGTSS — Tue, 27 Aug 2024 13:04:58 GMT

I'm not sure I understand what you're saying so I've replicated my workaround in an example Experience Builder project. In the screenshot below I've added a web map to an Experience Builder project. The web map uses a custom basemap called "City of Worcester Basemap". If I turn on the Basemap option in the Map widget, I get the duplicated basemap options - one with the thumbnail and the one with no thumbnail which I have circled. There are some other custom basemaps in the list which can be ignored.

I think it is confusing to the user to have 2 instances of the same basemap like this. So my workaround is to use the standalone basemap widget. If I choose our organization default basemap group, I can keep the "City of Worcester Basemap" unchecked. As shown in this screen shot, the only basemaps I have selected from the basemap group are the 2 enhanced contrast ones. When I do that I have 3 basemaps included in the basemap picker - the 2 enhanced constrast basemaps and the basemap used in my web map which makes a lot more sense than having 2 instances of the web map basemap included in the picker.

Hi, @WorcesterGTSS is it possible for you to share me with this group so I can take a look at your case?

Re: Basemap Widget in new Experience Builder displaying current map

WorcesterGTSS — Wed, 28 Aug 2024 12:57:08 GMT

Yes - I did actually remove the "City of Worcester Basemap" I referenced above in my example from the group because it doesn't need to be in there, but I replicated the issue with the "City of Worcester Basemap with Buildings and Surrounding Comms" basemap in the group, encountering the same issues as in my previous example. Our basemap group is here.

I agree having it twice is too much. In Web App Builder if my Basemap in my Web Map Classic was name the exact same as the Basemap in the Gallery it just ignored the duplication and only showed it once. I found that if I change the thumbnail of the map that it is displaying in Experience Builder to the default thumbnail of the basemap that initially opens then the basemap gallery will take on that icon. I don't like that solution and I think ESRI needs to think about how this functions.

I am having the same issue. I have removed my main basemap from my basemap gallery so it doesn't show up (as it is already showing up with it being the basemap used for my web map) which is not very intuitive. It still doesn't completely work as the thumbnail is not the nice thumbnail I created for my basemap. I can't see where to update it either.

I went ahead and posted this to the Ideas Page if anyone wants to comment on that.
