[Talk-GB] NHS England open data - hospitals

[Tony Shield]

Good one.

I've looked at the two nearest to me  -

Blue - Chorley & South Ribble District General Hospital, Non Contentious 
as far as I can see

Green - Eccleston Health Centre. Several problems with the data - its 
not a hospital its a doctors surgery, it's already mapped as doctors 
with the name Eccleston Health Centre, the location is about 100m 
distant on Doctors Lane, the Post Code centroid has been used as the 
location; so not a good match.

I've used the NHS website where I think this data came from and my 
opinion is that the data is outdated and not regularly maintained.

I think the best that NHS data can be used for is spotting missing 
facilities but should not be used for auto-updating the map. As you 
suggest manual conflation may be best.

Regards
