FHODOT: the food hygiene open data OpenStreetMap tool
You don't need to install anything to use this tool; simply use the instance running on the OpenStreetMap development server.
Why use food hygiene (FHRS) data?
- It's a rich source of open postcode and address data that can be used in OpenStreetMap because it's published under the Open Government Licence
- It provides a useful reminder of establishments you already know about but haven't mapped, and can help find areas that would benefit from a physical survey
- When establishments disappear from the FHRS data this is a useful indication that they may have closed down or changed name (see also Robert Whittaker's Survey Me!, which uses data from this tool)
Features of the tool
- Allows efficient matching of Food Hygiene Rating Scheme establishments and relevant OpenStreetMap objects in the UK through JOSM remote control or iD
- Suggests matches between FHRS and OSM data (based on proximity and fuzzy matching of names) on the 'Suggested matches' map layer
- Shows issues such as outdated
fhrs:idtags or matches between objects with different postcodes (see red map markers and tables) or between distant objects (in particular on the 'Distant matches' map layer)
- Automatically parses FHRS addresses into the correct
- Shows matching progress by local authority district
Major improvements since the original FHRS/OSM comparison tool
- A much-improved user interface
- More efficient manual matching through JOSM remote control without having to view data on the FSA website
- Address parsing
- Continuous map scrolling without data being broken into districts
- Map-based display of progress by local authority district when zoomed out
- Includes data for Northern Ireland
- More maintainable code
Why not import the data in bulk?
- The locations of FHRS establishments are often inaccurate, sometimes being based on postcode centroids
- Although the tool can often suggest matches, these need to be verified by a human, and it can't find every match with an existing OpenStreetMap object
- Although the tool can often parse FHRS addresses into
addr:*tags automatically, addresses still need checking
- Mappers will sometimes spot and fix other issues whilst matching objects
