|The thin red line is my route plotted on the map.|
Compare the proximity of the path to the field boundary after the small circular wood just to the east of the path by looking at the 1:25 map below where the field boundary can be seen.

OS 1:50000 versus 1:25000
I have never liked the Ordnance Survey 1:25000 map. The colouration is too uniform and anaemic, and I don't get the immediate picture of the terrain as with the trusty 1:50000, and the one kilometre grid lines are difficult to see.
I have a bad memory of my 1:50 Northern Lakes which I spent good money having laminated. Those maps are massive, and this should never be opened in wind of more than an ant's breath. On top of Hallsfell Ridge nearing Blencathra summit with Tony I disobeyed the rule - the wind was so strong I was carried several feet off the path - the map set off northwards like a paraglider. I imagined some guy in a street in Carlisle heralding its arrival on air, and wondering. That is the second time I recall abandoning a summit attempt because of wind. Now here's a thought: perhaps that wretched map could be put to good use doubling up as a paraglider saving knees on those punishing Munro descents?
My post op walking, has been relegated to farmer's-field-footpaths with hedges, walls, barbed wire fences, and rickety stiles, and gates tied up with orange furry string impossible to unknot.
On Saturday I walked seven miles with about 850ft of ascent across such terrain, which whilst pleasant to view is irritating to navigate. I was using my Memory Map 3500 which carries OS 1:50 mapping.
The GPS projects a direction of travel arrow, so when following a footpath on the map you can adjust your direction to keep the arrow on the path on the map, and yourself on the path on the ground. If you let the arrow deviate by, say three millimetres that is enough on the ground to have you on the wrong side of a hedge, necessitating wearisome backtracking. The paths I was walking were new to me, and apparently rarely used being indiscernible on the ground. Now I have to concede the denigrated 1:25 map can be of use on this terrain because it shows field boundaries, but to have the whole country on Memory Map as I have for the 1:50 would be outrageously expensive.
I am looking forward to paths above the cultivation line where I know what I am doing, with my route printed on A4 from the 1:50 map which is usually enlarged from the original, because my printer is set to fill the whole of the A4 if the selected area from the map is smaller, which it usually is.
