Hello. I understand that for making state boundaries we need a ‘state’ attribute where we use the state name or abbreviation. What about for the congressional boundaries? That is using lookupBoundary(US_congressional_boundaries,district) what should the entries for the ‘district’ attribute look like? I tried the common abbreviations – e.g. AK-AL, CA-10, NY-19, etc. – but it doesn’t work. It just gives me back “a boundary”. Also, have the districts been updated in the database since PA had there maps redrawn this summer?
