Apologies in advance, as only just signed up for ArcGIS online this AM.
I have created area layers through the 'add map notes' section to identify particular areas of Salford Quays, UK. I want to add data to each of these areas so that they can be interrogated (e,g which part of the quays has the highest environmental quality).
Despite an hour or so of searching i cannot find anything on adding your own data to a layer and then analyzing it. Any advice?
