How to upload a style to ArcGIS Online, to be used in the map viewer?

lvgr — Mon, 24 Mar 2025 16:06:36 GMT

I would like to upload a style to ArcGIS Online so I can use it in the map viewer when viewing a layer compatible with the style.

What I've done is create a new item with (in case of a style for lines)

ip = ItemProperties( item_type=ItemTypeEnum.STYLE, title=..., type_keywords=["lineSymbol", "web2d"], ) ... ...add(item_properties=ip, text=style_text)

I've added lineSymbol and web2d because it seems the viewer looks for items with these two type keywords when looking for styles.

style_text is the textual representation of a dictionary that looks like this

{ "items": [ { "name": "symbol name", "styleName": "style name", "symbol": { "type": "esriSLS", "color": [ 0, 255, 0, 255 ], "width": 10, "style": "esriSLSSolid" } } ], "metadata": { "styleName": "style name" } }

The item is uploaded correctly but it doesn't show in the map viewer in the 'Styles' panel, when I try to change symbol. I think there's something wrong in the style format, but I've found no documentation for it. I'd be nice if there was a JSON Schema.

Have not used python for this, but have shared a style to AGOL with Pro.

Once the style is in the Org, I opened map in map viewer, highlighted the layer, select "Styles":

Click on the Symbol style, then the Basic point (or whatever comes up) arrow, then click on the + sign:

This should let you add your new style to the web map, and can then be used for symbology.
