Well I guess that still leaves 31,000km of GB coastline (Ordnance survey figure) to investigate whilst using "Red".

 

How far from the land would you be to do that distance

"Inches" ?

 

That is the actual coastline length following every inlet and promentary, and going around each island (Anglesey, IoM, Skye, etc etc)

So if we considered the UK to be a rectangle some 600 miles by 200 miles what would be the length round the coast would be?? and if we were a mile offshore it would be?

When did you last use a one inch map?

 

Tuesday (but not 1" to a mile").

 

My walking "SatMap" GPS is set up using OS mapping at 1:25,000 or 1:50,000 and displays distance and heights in Imperial ( feet / yards / miles) (other settings are available)

 

Old picture:

 

Walked 5.29 miles

45 feet from my start position

Average moving speed 3.4mph

Current elevation 29 feet ASL

Total ascent gain 49 feet.

Maximum height achieved 55 feet ASL

Minimum height achieved 22 feet ASL

'So you haven't used a one inch map, then. I do still have quite a collection but only as museum pieces, really. Fill in the gap between NLS and current maps. (on line)

Of course, but unfortunately the OS have gone 'weirdly foreign' on us.

The last imperial scale OS maps were published in the 1970s 

 

The Ordnance Survey's large-scale mapping comprises 1:2,500 maps for urban areas and 1:10,000 more generally. (The latter superseded the 1:10,560 "six inches to the mile" scale in the 1950s

 

In fact the use of metric scale mapping in the UK dates back to 1911 which is probably before you were born.

My SD OS map card starts at 1:10,000 and goes up to 1:250,000,000

 

At 1:10,000 I can zoom in to individual gardens, street names etc.

But even the one inch maps (at that useful scale of 1:63,360) had grid lines at 1km intervals.

Only the Ordnance Survey ones. Bartholomews 1" maps have a grid every 2 miles
