Lets remind ourselves how we map from scratch (before signs):

  1. We measure + record what we see on the ground

  2. We ask local humans to supply the names/numbers/dates

I tend to think of 'loc_name=' as meaning "col-LOQ-uial name",
which seems appropriate in the circumstances.

Residental areas normally are mapped so that they include the gardens
belonging to the residences.  If the 'green space' is the 'gardens'
for the surrounding tower blocks this is perhaps correct?

A solution might be to ask whether somebody living in Queen's Park
Court would count the garden in the middle as being part of QPC?

For the nursery, it's could be less clear cut:  eg. is the nursey
perhaps on the ground floor with housing above?

[Based on developments today], Why not hold it at the Bluebell in
Attenborough on the evening of Wednesday, 8 January 2016[1].  There
are several rights of way across the Midland Main Line in the vicinity
in Attenborough:

  
http://overpass-api.de/api/convert?data=node[%22railway%22~%22crossing%22]%2852.85,-1.26,52.92,-1.2%29;out;=openlayers=14=52.9=-1.23

These road/foot/bridalway level crossings are the first 7 level
crossing (previously 9) after leaving London (200 km).  All are
concentrated in Attenborough between Trent Junction and Beeston.

-Paul

[1] Verbal confirmation that a public consultation has been scheduled
for 8 January 2016 15:00-19:30(?) in Attenborough Village Hall.  It
would be very useful to have each of the level crossings re-surveyed
and micro-mapped as ground-truth basemaps of the status-quo.

The changes are one thing; but the automated non-responses are going

I'm wondering if the 'alexkemp' has previously received the

Since 1999 the London dialing code and numbers have been:

  (020)  

Following the exhaustion in the '7xxx ' and '8xxx ' ranges a
decade ago in c.2005, the '3xxx ' London blocks have been used for
issuing new numbers.[*]  See:

If you moved into a new house in London, you too would likely receive
a '3xxx ' number.

Apologies for being unclear. There is no such thing; quite simply:

  020

Is the London dialing code, and has been for over 15 years.

Local numbers in London have eight digits and you cannot make
assumptions beyond that.

Fifty-years ago you, could, but not in the present day.

Black-numerals-on-white-circular is mph, White-on-black is kph.

Best place to see this is at the end of the platforms 6-11 at St
Pancras, where both are present based on the depature route.

Tram diamond speed limits are in kph.
