The graphs below represent statistics relating to the OpenStreetMap GB Quarterly Project 2016 Q4, which involved using Food Hygiene Rating Scheme open data to enrich the map. Links between the OSM and FHRS data were created using the OSM fhrs:id
tag, and for a match to be considered successful, the addr:postcode
tag had to be added to the OSM entity.
The data used for the graphs below was gathered using the FHRS/OSM comparison tool and relates to the time period between 10th October 2016 and 1st January 2017. Some figures for the districts of Dumfries, Haringey and Kingston upon Thames have been approximated because of sudden changes in the FHRS data during the project.
The percentage of FHRS establishments successfully matched (i.e. including a matched postcode) has been improved by a factor of 2.97 from 1.7% to 5.04%. The percentage of FHRS establishments successfully matched (but with a mismatched or missing postcode) has been improved by a factor of 2.63 from 2.14% to 5.63%.
As a result of the project, 238 districts out of 377 now have at least one successfully matched FHRS establishment as opposed to 166 districts.
