New project for 2018 - OS One Inch 7th Series map coverage

[Steven]

Newly on SABRE Maps - Sheet 95 (Blackburn and Burnley) Revision A from 1954.

I can imagine at least one well-known member poring over this one to find all the differences, so I'll not put any spoilers here this time!

[Steven]

Three more today, all from 1962.

They are:
* Sheet 115 (Pwllheli) Revision C
* Sheet 129 (Ludlow) Revision B//
* Sheet 159 (The Chilterns) Revision A/*/

Let me know what fun things you find!

* Sheet 159 (The Chilterns) Revision A/*/

That section of the A40 at Aston Hill looks like a total nightmare compared with the rest of the road!

You'd actually be surprised at how little the fundamentals of the network have changed around Blackburn since 1954. Most of the really noticeable changes have occurred since 1980...

[Steven]

Two more One Inch 7th Series today, both to the 1961 layer.

They are:

* Sheet 90 (Wensleydale) Revision B
* Sheet 157 (Swindon) Revision A/

The latter means that we now have every revision of Sheet 157 available online, so that's nice!

Couldn't resist.

MORE MAPS! LESS PUB!

* 1956 - Sheet 64 (Berwick-upon-Tweed) Revision A
* 1958 - Sheet 95 (Preston) Revision A/
* 1960 - Sheet 175 (Okehampton) Revision A
* 1967 - Sheet 185 (Newquay and Padstow) Revision A/*

Yes, you too can learn all about Preston immediately before the opening of the M6 Preston Bypass; and that's every revision of Sheet 64 now online as well.

Thanks Steven - we've hit a minor issue in that Oxfam appear to have closed their bookshops, and I've been grounded - so the supply of new maps from me might dry up for a bit...... If you start to run low, let me know and I'll wander to the post office and send you some more

...and see the emergence of the runways at the aerodrome at Newquay between the 1961 and 1967 sheets

I've got Sheet 61 (Falkirk and Lanark) 1966, if this is needed?

[jon81]

It has the original section of the M8 Harthill bypass. Also sections of the dual carriageway A80 and A876 around Denny before they were upgraded to motorway.

[c2R]

I've got Sheet 61 (Falkirk and Lanark) 1966, if this is needed?

Is it the one with Revision Code B?

If so,it looks like we've not got a copy, so yes we need it! https://www.sabre-roads.org.uk/wiki/ind ... ge_project

Have you got a scanner?

[jon81]

Yes, it's a B version. I can send a link to dropbox if that's ok?

[c2R]

Execllent, yes, that sounds good. Here is some information on map scanning: https://www.sabre-roads.org.uk/wiki/ind ... p#Scanning

The critical thing is that each section must overlap those to either side by a reasonable amount, or the process to put them back together as a single sheet will fail. We also need the margin areas too, not just the map itself - partly because we then have the revision code information that gives us exactly which map it is, but also because we need the grid reference or latitude/longitude information from the map.

Each individual scan needs to be in a JPG format, preferably at 400dpi, although 300dpi scans can be used. The scans need to be provided to a team member (often by the use of online storage such as Dropbox, Google Drive, or OneDrive), who can then pass them on to the next stage of the process.

It's easiest if the individual scans are labelled in a "row, column" or "battleships" format, so A1.JPG would be the top left-most scan, A2.JPG the one to the right of that, and B1.jpg the leftmost scan on the second row.

[jon81]

Thanks, just sent the scans to Steven.

[c2R]

Thanks, just sent the scans to Steven.

Great, thanks both!

Time for the now-traditional end of year update.

We now have:

425 indentified active One Inch Seventh Series sheets on SABRE Maps (up from 294 last year), with an additional 46 still to have their exact revisions identified (down from 63 last year); for a total of 471 different sheets available. That means that as of today we have around 2.5 times the number of OS One Inch Seventh Series sheets available on the next largest georeferenced online repository that we know of (the NLS).

In addition there are now 38 individual sheets where we hold every single revision ever printed (up from 26 last year), and a further 22 individual sheets where we hold a copy of every sheet that is currently out-of-copyright (up from 9 last year), though this is a moving target as more sheets drop out of copyright.

2020 has been relatively quiet in terms of One Inch Seventh Series this year, as I've been concentrating on New Popular, post-war Scottish Popular and Fifth Edition mapping, taking us all the way back to 1931 where it's been possible to do so.

So, as it's the start of 2021, and maps with a copyright date of 1970 have now become available to us, I've added the following:

1973
Sheet 102 (Huddersfield) Revision B/*/*/*

1970
Sheet 87 (Isle of Man) Revision C
Sheet 160 (London NW) Revision C
Sheet 161 (London NE) Revision C
Sheet 170 (London SW) Revision C
Sheet 171 (London SE) Revision C
Sheet 172 (Chatham and Maidstone) Revision B
Sheet 177 (Taunton and Lyme Regis) Revision B
Sheet 178 (Dorchester) Revision B
Sheet 181 (Chichester) Revision B
Sheet 182 (Brighton and Worthing) Revision B

That means that we now add 1970 as the second year where we have copies of every map published in that year online, and 50 sheets where we have every revision ever published online, which is over double this time last year. There's now 466 identified individual sheets, plus the 46 still to have their exact details to be confirmed - some more of which should now be possible to be resolved.

We're now heading into what is possibly the most interesting era with many of the early motorways and ringways in full swing.

just a question -

how easy would it be to provide a link to each map added, or is that too much of an ask

I'm not sure what you mean? It's entirely possible on Maps already to generate a link to a particular location on a particular layer.
