I guess this topic will have been debated before

- however, can some one concisely explain to me why...

... on my Memory Map Navigator Software for The Lake District I
have a c100m discrepancy between position:

N 54degrees,30 seconds, E 3degrees and the Graticule Intersection
marked on the map.

This location is just SSE of the outflow from Grisedale Tarn near
Fairfield.

I have yet to take my GPS into the field - but my cursor shows a
point approximately 100m ESE from the Graticule Intersection. as
marked.

I ask as I was idly thinking that such a spot would be a cool
location for a Geocache - but only if I can determine exactly
where to put the box!!

If I could understand the question, I might be able to help.

On my Anquet version of the same, I get exactly 54.30.0N, 3.0.0E
when the cursor is on the graticule.

I think Glaramaraman has entered the co-ord into a co-ord menu box and
it has actually placed the waypoint C100m ESE of the intersection....I
think!
