Thanks to Brian Quinion's fantastic work on location search code we now have a very useable street index document for Birmingham which we have sent to Birmingham City Council for them to do a comparison with their official street index. Ideally we would have taken their list and croudsourced the review but hey, that's another story!
For those interested, the data is available in an Excel spreadsheet [1] and also a hard copy PDF [2]. It's based on data within the Birmingham boundary as we know it. Because we don't know exactly where the boundary is we may be missing or including some streets. What BCC send back should help us better define the boundary. Note that the list is produced from a planet dump that's about 2 weeks or so old. A couple of words of caution. Firstly the west midlands contributors haven't been through this list themselves yet to check for obvious bugs. There are bound to be some spelling mistakes as well as some unconnected streets because the data is not topologically correct. These should be easy to spot and fix so we'll be working on that. Also don't put too much reliance on the postcodes. The postcode data that's in the spreadsheet is generated from polygon data and not necessarily from information carried on an individual way, as a result it may not always report the exact correct postcode or part postcode for the way. The lat/lon values will me more precise.
