Those of us with a map bent - or bent map - may like to know that our friends at
the Ordnance Survey are publishing new editions of the Landranger maps of North
Wales in January.

God willing, they will be sheets 114 (Anglesey) edition B5, 115 (Snowdon)
edition C3, 123 (Lleyn Peninsular) edition B3, and 124 (Portmadog) edition B3.

I wonder if the Maybush scribes will get the detail of our favourite railway at
its southern, urban end right? (cf Explorer sheet OL18 edition A2.)

I would hope so - they've been told, and a kind letter from the Director General
of the OS is on file.

Remind me again what's wrong with the Welsh Highland Railway on OL18 edition A2?
The on-line versions seem alright to me - I've attached zipped samples [not
reproduced, but showing the railway line at both 1:25000 and 1:50000 scale].

Very interesting. My paper copies of LR124 and OL18 show a noticeable lack of
the new harbour branch line (or main line as we should call it) from Pen Y Mount
to Spooner's Bar [at Harbour Station]. I've just looked at the OS GetaMap and
lo! there it is!

This is very important for OS fans, as it's the first example I've seen of an
on-line version containing new detail not seen on the current paper edition.
I've got to think about this.....

I've copied this email to my friend Bill [and Richard Oliver] who will, I'm
sure, have some thoughts on the matter.

Don't go away

This is new to me! I don't know what OS's updating procedures are nowadays, but
it would not surprise me to learn that, instead of updating an area to fit in
with the publication/reprint cycle of a particular sheet, i.e. in the few months
immediately before a new printing is scheduled, that instead they are updating
tiles as new information becomes available. This would bring small-scale
revision into line with what is now well-established digital large-scale
practice. It might also nudge some people away from buying the standard
published maps and into OS Select!

Best wishes,

Richard

The plot is certainly thickening. I wonder if we're heading for the editionless
edition?!

Thanks. We effectively have 'editionless editions' with the large-scale digital
stuff already, where just an annual updated version of the whole database is
supplied to the legal deposit libraries!

The example here in Porthmadog give an on-line publication date a good six
months ahead of the paper version. Are there any more examples out there?
