The first job would be to try matching up places from each source and spot the conflicts.

We get the locality hierarchy because each place can have a parent. The rough perimeter comes out because every Stop Point is also associated with a locality, so one can put a rubber-band around all the stops that claim to be in Cambridge or a suburb of Cambridge and one has an approximate boundary for the place. Every bus stop also says which administrative area it is in (a county/ borough/PTE) and so we get approximate authority boundaries as well. Other stuff - every stop should have an associated street name and a direction of travel when it leaves the bus stop. This might help us with naming streets or at least cross-checking our streets with theirs. > I imagine I could help if you want/need assistance with importing.
