Tooltips on BasemapGallery with LocalBasemapsSource from GIS Server

ForrestLin

I created a BasemapGallery with LocalBasemapsSource from map service hosted in GIS Server:

const myBasemaps = [

new TileLayer({
url: "https://myhost.com/arcgis/rest/services/OCPA/Aerials2023/MapServer"

})

];

const basemapGallery = new BasemapGallery({
view: this.view,
container: "basemap-gallery",
source: new LocalBasemapsSource({
basemaps: myBasemaps
})
});

How to setup Tooltips like:

Thanks.

Hi @ForrestLin,

Your LocalBaseMapSource will contain one or more Basemaps. If the Basemap is coming from ArcGIS Online (or ArcGIS Enterprise) then you can edit the tooltip text in your portal: it is the description you give to the item.

Alternatively, if your Basemap is coming from another source, you can give your Basemap a title which will pop up in the tooltip.

See code snippet below. For the Basemap which is based on the WMTSLayer, it is the title "BRT Achtergrondkaart (PDOK)" which will show in the tooltip.

HTH,

export { baseMaps };

Hey @Egge-Jan_Pollé

I did the same as you did.

const basemap = new Basemap({
id,
title: "Aerial 2023",
thumbnailUrl,
baseLayers: [
new TileLayer({
url,
})]
});

But how to setup tooltip: "Orthos imagery [Date: Jan, 2023]", which is different from title: "Aerial 2023"?

Thanks.

Hmmm, what is the source of your TileLayer? Can you set a description in the portal, as indicated in the first part of my answer above...?

ForrestLin

Hey @Egge-Jan_Pollé

The source of TileLayer is from ArcGIS Server, not from ArcGIS Portal.

How/Where to set a description in ArcGIS Server?

Thanks.

Hey @Egge-Jan_Pollé

If the source of my TileLayer is from portal and set the summary, then the tooltip works.

I'm wondering if it can be set in code.

Egge-Jan_Pollé

Hi @ForrestLin,

Thanks for checking this out. I think it works 'as designed': Esri, of course, wants you to use their portal, and - as you indicate - the summary you set there will appear in the popup.

There is no way, as far as I know, to set this popup text in the code. Can someone from Esri confirm? Code wise, you can only set the title, which will then appear in the popup (like in my code snippet above).

Thank you!
