Helper IHey DuncanP -
No worries. I think it's all related (regarding the mismatches). Our underlying service used to give error codes for unmatched addresses, which client applications could filter out or handle differently at their discretion. Now the backend service attempts to find a match no matter what - resulting in some undesireable matches. We're working with the team responsible for this behavior to get it modified, and then we'll update our code in turn. It won't get fixed overnight, but rest assured we're working on it.
Regarding the bisected districts and weird shapes you might be seeing - in order to keep the speed high, we are 'generalizing' the shapes - that's to say, we're making the shapes a lot simpler than they really are in order to transmit them across the wires quickly. It's a balancing act - we want them to be simple enough that they are fast, but we don't want them so simple that they lose the ability to represent the thing they're supposed to represent. Please let me know if it's erring too much towards the latter and we can take a look at tweaking it a bit.
I'm really happy to hear that despite some hiccups you're enjoying the visual!
Advocate IIHi scottball
I totally understand the speed considerations: I've tried plugging actual boundaries into the shapemap visual and it's woefully slow.
I don't know whether it's possible to say that when part of a district ends up completely within another one, it could be subsumed entirely? For example, the NR21 district below:
Could the bit of the shape to the left be ignored entirely? In reality, it's a small bit that sticks out past RAF Scunthorpe:
If it were possible to remove the extra bit rather than raise the detail level to go around it, then the speed wouldn't be compromised.
On another subject, if we choose to represent locations as points rather than boundaries, it's no longer possible to use postcode areas or districts as locations. Is that something that might be implemented at some point, perhaps using the centre of the postcode area or district as the location?
And yes, I am enjoing the visual, it's just what I've been waiting for!
Best,
Duncan
