I have remote staff who are only going to have access to Collector and our ArcGIS Online (organizational) account. Our license level for Arc Server does not (currently) allow us to create feature services. I can create an initial (AGOL) map for them to work with which consumes map services we host, it’s the editing part that’s the problem.
Is there an object/item I can create/upload to AGOL that will allow them to do their editing against it? The only ESRI tutorial I have found does not describe how to do this (if it is even possible).
You can publish layers from ArcMap to AGOL as Hosted Feature Layers. Publish hosted feature layers—ArcGIS Online Help | ArcGIS
Share the items (My Content) with required groups/organization/public.
These layers can be opened in Collector for ArcGIS and edited.
