Old OS maps for Welsh Mountains

[maubp]

I have uploaded a few scanned and calibrated maps from southern
Snowdonia, Wales, UK:

(1) Cadair Idris (aka Cader Idris) (~1MB)
(2)Aran Fawddwy (and Dinas Mawddwy) (~2MB)
(3)Maesglase and Waen Oer (~2MB)

For space reasons I have only include the images in PNG format.

In each .ZIP file there is also a .GUX calibration file for GPS Utility, and
a .MAP calibration file for OziExplorer.

Regarding the copyright, this is from the OS website:

These are scanned from an old cloth backed one inch/mile Ordnance
Survey map published in 1947 (Sheet 116, "Dolgelley", or "Dolgellau"
as it is now spelt), which is well over 50 years old, so out of
copyright now.

Unfortuately, I think this is the oldest OS map that I own. I have
some "Seventh Series" too, but they are still in copyright.

P.S. There are a few more bits I could scan in, like the Rhinogs or Arennigs...

P.S. I would hope that most readers on the forums had taken this to heart already, but remember you should not just depend on the GPS (+handheld computer) for mountain naviagtion, especially if using old maps like this.

Always take a (recent) paper map and compass with you when hill walking, and know how to use them!

I was more interesting in things like old railway lines, and changes in the forestry - which are quite substantial in this part of Wales.

P.S. The contours and spot heights on these images are in feet (which is to be expected given their vintage). According to the map legend, the contours are every 50 feet.

I've tracked down another map of the same vintage (first published 1947 so out of OS copyright): Sheet 107, Snowdon.

Will probably try scanning in some of it at some point...

I'm getting CRC errors when attempting to extract the .png files in each of those archives?

Interesting Darren, looks like something went wrong there somehow. I have re-uploaded the files to my ISP, and double checked I can download them OK now. Sorry about that...

I would be interested to here how the calibration looks to you:

The .GUX (GPS Utility) and .MAP calibration (OziE) files both use the OS grid, so seem to be pretty good (baring the limitations of the original scan, which is slightly distorted).

I have also included a .JPR file, which I failed to get to work with Fugawi (I tried their demo), but should work in Memory Map (again, I used their demo).

The JPR format uses Latitude and Longitude for calibration, but there was something not quite right when used with Memory Map...

(See also this thread, converting .MAP files to .JPR files)

Excellent, I'm reviewing Pathaway (www.pathaway.com) at the moment and they calibrate fine in the excellent PC Calibration Applet.

And as I was born in North Wales these maps are great, I have spent many hours on Snowdon, Moel Eilio and Moel Siabod.

Another one, showing the increase in forestry quite effectively:

(5) Moel Hebog and the Nantlle Ridge (~2.7 MB)

Another section from Sheet 107, Snowdon.:-

(6) The Glyders range (~3.1 MB)

Here is some of this map, using GPSU and then some annotation in Paint Brush showing where I went last weekend on Tryfan - and highlighting that the GPS was having trouble on the north face...
