I've been making a push recently to seek out postboxes in East Kent. CT1, CT2, and CT5 are already shown as complete on the Dracos website. Now we've only got one box left to find in both CT3 and CT4 before each of those is complete as well.
Finding some of the boxes has been particularly tricky as some the descriptions are pretty useless. For example one of the CT4 boxes is described as "Stone Street". To anybody local to me that means the Roman road of the same name. Pretty much the whole road is within CT4, which covers a sizeable portion of the East Kent countryside. Basically the description narrows it down to a search of about 8 miles in length of road, or about 80% of its total length. Now that's helpful.
I've mainly been concentrating on the CT postal sector, but also straying over into the neighbouring ME and TN sectors from time to time. Today I'm pleased that we've reached a milestone of sorts for CT: 2/3 of all of the boxes have now been found when comparing against the Dracos data. That equates to 708 boxes.
In searching out some of the remaining boxes I've found that a few typos have unfortunately been made in the refs for I'd mapped a long time ago. Thus they weren't showing up as mapped when the Dracos updates from OSM data each Sunday. Some Postgres queries quickly uncovered candidates for these though, followed by a trip to the boxes themselves to confirm their correct refs. A further Postgres query reveals that there are a few boxes elsewhere in the UK with duplicated refs. So, if you live near one of these boxes then it may be worth another check:
Now that we've got reasonable approximations to the outward postcode sectors in East Kent I've been able to make decent use of it to visualise the distribution of the membership for the cycle campaign group that I'm on the committee of. It's really useful having the data available in a compatible licence. Now, if only the Royal Mail would realise this too and open up their data...
