[Qgis-user] How to Make a project layer editable

[Randal Hale]

To be honest - I'm not sure if ArcGIS will edit coverages any more (just 
checked). It will convert to and from but I didn't see anything that 
indicated edit.

I think your best bet is to convert it to a shapefile (or 
postgis/spatialite) if possible. If memory serves me right you could 
store a mix of geometry in a coverage so watch as you are converting.
