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!

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...

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!

* 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.

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?

From the SABRE Wiki: SABRE Maps/Seventh Series coverage project :
This SABRE Maps Coverage Project is to provide online coverage of the One Inch Seventh Series and associated maps.
This was the first Ordnance Survey mapping at the One Inch scale to be a single series across the whole of Great Britain, and is useful for us to have as it shows mapping at a relatively detailed scale during the major

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.

From the SABRE Wiki: SABRE Maps/Adding a map#Scanning :
The process of adding a map to SABRE Maps can seem quite complex, and offputting for people looking at how they can help; but actually the vast majority of steps are either quite simple in themselves, or have had tools written to make them simple to complete.
The process itself can be split into several tasks, of various levels of difficulty. This guide will look at a simple level at the various stages in the process, with links to more in-depth information about each stage. It should be

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.Steven wrote: ↑Tue Dec 31, 2019 17:07 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.
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.

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.
