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

Question

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"
