Write documents describing exported data

[Nick Burch]

Should export in a similar format to currentlist from freethepostcode, to be run on a nightly basis.

We'll want the following:

• freethepostcode only
• npe only
• outward (average)
• outawrd + 1st inward (average)

[Nick Burch]

Code committed to svn to do this - source:trunk/npemap.org.uk/scripts/export/

Need to set this up to be run on a nightly basis - Dom can you do this?

Probably just want three of the four exports for now:

• -npeonly
• -outer
• -outer1

Once the nightly export is happening, we can link to them from the site

Hmm, we can start running this but I would like to improve it before we publish it.

In particular I would like to do some analysis when we average postcodes so that we can detect gross inaccuracies.

Eg of each record of an OX1 postcode, throw a warning if they are more than 10k apart (is 10k enough for the outward? Dunno, needs testing) and 1k for the outward (again might not be enough).

[Nick Burch]

I think we should probably have the sanity checking in another application. We'll probably want it to show us where the postcodes are, so we can take a look and see if they look sane or not

I guess the app would run, find the averages, then report any postcodes past the threshold with a summary. From there, you can click through to visualise them (distance not too big, but high) or delete (distance shown to be massive)

Right, we now have http://www.npemap.org.uk/cgi/get-distant-postcodes.fcgi to report which postcodes look a bit out, based on the averages
