I need to use military symbology for a WFS hosted on Geoserver in Web Map. Is this possible? how?
If you are using ArcGIS Enterprise, if not already available, you can publish a military dictionary desktop style (released with Pro) as a web style by: choosing the symbol standard you want to publish in the Dictionary drop down, clicking on the "More" drop-down and choosing "Add dictionary to project", switching to the Catalog pane where you should now see the military style under "Styles", right-click and choose "Share as Web Style". This will create a new portal item in Enterprise, which you should now be able to search for and added in the Symbology pane as in Step 4.
Here is an example of a web map showing the dictionary renderer on a WFS layer:
Please let me know if you have any questions or if this workflow doesn't work for you.
