Bristol historical/community POIs

Bristol City Council have a "heritage map" Know Your Place (also available in a non-Silverlight version) with historical/community POIs that could be visited and added to OSM.


Originally, Bing was the best source of imagery with a high degree of resolution and contrast -- a great number of buildings were traced using Bing imagery (before end of 2017).

Towards the end of 2017 a new set of Bing imagery was made available -- it is more up to date, but unfortunately, doesn't have the original resolution, or contrast -- and more significantly has an offset compared to the original set of Bing imagery -- so that previous tracing appears offset. If using 2017+ Bing imagery (generally grey in colour) then please adjust its offset to match already mapped features.

At present at the start of 2018, the original Bing imagery (or a variant thereof) is available in JOSM as the "ERSI Clarity layer (beta)" -- it is probably the best imagery to trace from (given previously mapped buildings) -- but care should be taken where it could be out of date.


Lifecycle process used by some Bristol mappers.

  1. name is the name -- so don't add extra "(Closed)" or whatever
  2. Only to add a name if there's some signage / something else that can be seen -- or maybe a planning notice stuck outside
  3. If it's not open yet, then use the same tag as normal but add "proposed:" in front -- which makes it really easy to fixup when it does open
  4. if it closes -- then add "disused:" in front of the main tag -- and remove old phone #, website, etc. Some people will put "old_" in front of phone #, etc. instead -- might have an advantage if it isn't really closed -- but in general not sure how useful it is
    1. if the sign is still up, then it is a useful aid for navigation, so leave the name on the object - don't move it to disused:name (a disused:name doesn't make sense -- it either has a name or doesn't).
    2. if the sign gets taken down, then remove the "name" or maybe change it to "old_name", or if really well known as some local landmark then "loc_name" / "alt_name"
  5. if it's "just something planned / just read in the paper" -- then add a note, until it's actually surveyed (remember to log in before adding the note)
  6. If there's a housename / something carved on to a wall -- then use addr:housename to capture it -- e.g. old police station in Bishopston
  7. if it was an old church, then maybe building=church, rather than building=yes -- some people add building:use=residential too -- there's also historic:building.

There may well be better ideas -- there seems to be a discussion at the moment on -- about "tagging for decaying features" which might have some info'.
