Thanks for the updates. They look like they will be useful.<br>
<br>
Could you clarify how the 'distant matches' are calculated? I'm
confused by a couple of the errors it's thrown up:<br>
<a class="moz-txt-link-freetext" href="http://gregrs.dev.openstreetmap.org/fhrs/district-270.html">http://gregrs.dev.openstreetmap.org/fhrs/district-270.html</a> <br>
<br>
'Sam Wellers', 'Longvernal Primary School' (at the very bottom).
Their fhrs:ids match. There's no postcode in OSM & the FHRS
postcode is close to it's true location. Their dashed lines point to
the same location.<br>
<br>
There's a third establishment at that location.
(<a class="moz-txt-link-freetext" href="http://ratings.food.gov.uk/business/en-GB/205481/">http://ratings.food.gov.uk/business/en-GB/205481/</a>) but it appears
to have a redundant postcode in FHRS.<br>
<br>
Thanks<br>

<div class="">*Distant matches*</div>
<div class=""><br class="">
</div>
<div class="">There is now a table at the bottom of each district
page listing those FHRS matches for which the OSM and FHRS
positions are > 500m apart. For these matches, the overview
map also has a dotted line showing the difference in positions.
N.B. OSM positions are usually more accurate as FHRS positions
seem to be reverse-geocoded from postcodes. These distant
matches may therefore indicate a problem with the FHRS data
rather than OSM data, but are worth checking.</div>

<div class="">*Duplicate fhrs:ids*</div>
<div class=""><br class="">
</div>
<div class="">There is also a table at the bottom of each district
page listing all of the OSM entities which have an fhrs:id tag
that is shared with at least one of the OSM entities in this
district. This can indicate an error, although sometimes FHRS
IDs do correspond to more than one OSM entity.</div>
<div class=""><br class="">
</div>
<div class="">The suggested matches map no longer suggests matches
using FHRS IDs that have already been assigned to an OSM entity.
(Thanks to spindr for spotting this one.)</div>

<div class="">*Updating OSM data*</div>
<div class=""><br class="">
</div>
<div class="">The update script now runs a bit later in the
morning (after the Geofabrik OSM extract becomes available) and
thanks to some optimisations, takes much less time to complete.
The lag between updating OSM and seeing your updates appear in
the comparison tool should therefore have reduced a bit,
although not disappeared completely!</div>

<div class="">I hope you continue to enjoy using the comparison
tool. As ever, please report any bugs or feature requests on
