[Talk-GB] English Vineyards

[SK53]

I thought I'd see if using a clustering approach might give a better handle
on how many we have mapped in reality. I clustered centroids using DBscan
clustering with a distance of 1km (some parcels are quite big) and keeping
isolated parcels as a cluster. I then split any clusters by name and/or
operator. This yields about 350 distinct entities, but many parcels have no
name & these are assigned separately, so this is still an overestimate. The
basic conclusion is that a name or operator tag on each vineyard area would
be useful, but it also means there are plenty more to find.

PS. centroid data converted to OSGB; ST_ClusterDBScan(geom, 1000,1) and
then a standard GROUP BY on name and cluster id/
