To be sure the projection distorts sizes so Greenland appears about the

Dear Geoff,
Given that you have checked the Ordnance
Survey's A guide to coordinate systems in
Great Britain you will know everything
that I know on this and, no doubt, much
more besides.
What I didn't quite deduce from the document
is how individual features get into the
grid squares! You
that these basic facts were still true.
What should I now believe?

Dear Geoff,
I share your lament...
I thought that I understood the principles
of the OSGB but since Keith said that it is
not strictly based on a transverse Mercator
projection, I am now confused again.
Well, the Ordnance Survey certainly WAS based

Looking at Linda's map, are you rooting for Scottish independence?!

Yes, the Mercator projection distorts areas
Dear Tony,
What a fun thread you have spawned!
Mercator is possibly the most famous
Belgian, not that Belgium existed in
his day but let's overlook that detail.
The mathematics of Mercator's projection
is quite challenging. Certainly Mercator
himself didn't understand it!

A simple rectangular projection where Longitude
is the X coordinate and Latitude is the Y coordinate
also has straight and perpendicular lines. And it
can go all the way to 90 North. Of course, longitude
is very distorted at the poles.
