Has anyone been able to symbolize flow direction of sewer or storm sewer pipes in ArcGIS online? if so, how'd ya do it!
Brett,
How is your data stored? If you're using ArcGIS Server and publish a Map Service, you should be able to retain your symbology from ArcGIS Desktop (thus, showing the arrows/flow going the right way, etc.).
I'd like to know as well. I'm not using ArcGIS Server....just uploading to my AGOL account and displaying the feature service in a webmap. I think it'd be a really useful feature to have in the symbol selector in AGOL. Perhaps they could add it to the pattern selection dropdown?
