Can I use my own polygon pattern for symbology in ArcGIS Online?

EmilyLee2

Hello GeoNet,

I wonder if it is possible to use my own polygon pattern for symbology on ArcGIS Online like points do. I have a set of standard pattern for land use, but they are not solid colors.

Ex:

And when I tried to pre-set the symbology before publishing the service online, those came out empty (hollow with no color) or solid black instead. Like this:

Any idea please?

Thank you!

Emily

Hi Emily,

Currently hatched symbolgy like your examples are not supported in features services that are hosted in ArcGIS Online - unfortunately I can't find any documentation on it but there is an idea you can vote on: https://community.esri.com/ideas/6678

If you have access to an ArcGIS Server, you could publish your layers to it - this retains the symbology. Then the layers can be added to your ArcGIS Online account.

It is possible to apply line fill or marker fill symbology on a Hosted Feature Service by modifying the service definition at the item’s REST endpoint - these symbologies seem to be supported by the current web map specification, but are not built into the graphical user interface. This process is a bit of a workaround, but it is possible.

Navigate to the Admin REST endpoint for the hosted feature layer. See here for how to do this.

Follow the directions in the previous link to update the service definition, but instead of modifying the query limit modify the drawingInfo section of the JSON - under "drawingInfo" will be arrays for each symbol defined on the layer - the ones that begin "type":"esriSFS"define the polygon fill - the ones that begin "type":"esriSLS"define the polygon border symbology.

For each symbol in the layer modify the JSON to the attributes for the line fill or marker fill you are looking for. Full lists of supported symbol options:

- simple fills

- picture fills

- picture markers (for points)

- simple markers (for points)

- simple line symbols

For example: Changing "type":"esriSFS","style":"esriSFSSolid” to "type":"esriSFS","style":"esriSFSCross” would apply a cross hatching symbology, and retain the existing fill color. It can be helpful to use a JSON formatter when filling in these attributes, like the “Pretty JSON” plugin for Sublime Text.

Navigate to the layer’s REST endpoint on the Hosted Feature layer’s item page, and view the layer on a map. The symbology does not seem to be pushed to the AGOL item, but will show up if you add the layer to a web map using the REST endpoint URL as opposed to referencing the item.
An example of this: hosted feature service, map showing the symbology.

Hello. Your post really helps a lot of people. I thank you again! When I update the color RGBA and click the 'Update Service Definition' on the bottom, it doesn't update when I check the layer on webmap when adding it from the URL. When I go back to the Admin Update Service Definition page, the RGBA #s went back to original. Am I missing some step? Thank you.

This is great! Thank you very much!

Thank You for the info!

However, I see that your example explains how to change the fill style (and it works fine) - but is there a way how to change the color and width of the hatched lines?

Or the best way to apply that sort of a fill would be using a picture fill with transparency (how I have applied the hatched fill symbology so far)?

Thanks!

DeVoe_William

You should be able to change the color in the drawingInfo section of the JSON, but I do not think there is anyway to change the width of the lines, or to overlay multiple line layers as you could do in ArcMap. For this sort of complex symbology you would have to publish a service through ArcServer not AGOL.

Thank you!

Yes, this worked great. The only thing I had to change was in navigating to the Admin REST endpoint. The direction to Replace "/" between the service name and FeatureServer to "." resulted in an error. Just inserting "admin/" was enough.

I had defined hatches in ArcMap, prior to publishing as a hosted service, which was supposed to have worked. Two of the three layers with hatching came into AGOL just fine, but the third came in as a solid. No idea why...but this solved the problem. Thanks again -

Seems that Map Viewer Beta works well with hatched symbols published from ArcGIS Pro. I can even change the hatched line color. But not line width.
