Thanks for the welcome! I am not sure what kind of map it would be. There are economic, non-economic and invisible elements that are place / context specific. City of Birmingham Symphony (England) and Seattle Symphony would have shared as well as distinct elements. Each has a physical, socio-economic structure as well as a distinct territory. What are the elements of data and phenomenon that tells the story, that gives voice to the elements of place and context? Are these the right questions to ask?
