Can a map service be exported to a feature layer on ArcGIS Online

[NathanFreitas]

I have been trying to work with a previously developed web app that utilizes a web map that has a feature layer. The details of this feature layer references a map server url i.e. http://gisdptdev.admin.adams.county/arcgis/rest/services/ASR/ASR_Comparables/MapServer/0

I created a new web map with updated data published as a map server even when I specify the specific layer with similar url as above the web app cannot see it. It seems that I need a feature layer but how do you create a feature layer from a map service?

When I try to create a feature layer in ArcGIS online using the map server url as above I get an error saying I need to reference a feature service.

My IT department says the comparables service was never a feature service or layer yet I can see it in our organization account. They cannot explain it. Any thoughts?

Nathan,

  If  "I get an error saying I need to reference a feature service" then you need to add feature access to your map service when yo publish it. This will give you a FeatureServer along with a MapServer so your url would look like "http://gisdptdev.admin.adams.county/arcgis/rest/services/ASR/ASR_ParcelMACCT/FeatureServer/0"

You must be doing something that is requiring an editable service for it to be requesting a "feature service"

I assume ( still trying to figure this app out because I did not write it), that the feature layer is needed for querying. Not editing per se but allow for searches. For some reason I cannot use layers from map services as they do not show up in the layer list and the widget does not work because it cannot find the layer. I'll look into the feature access for the map server, thank you for the lead.
