Well, thank you both.

Not soon, but will try to generate some very simple maps with
alternative viewpoints and projections. Will attempt a couple of
azimuthal maps centered on Buenos Aires, for instance. Azimuthal maps
have a very important property, in that they keep great circles
passing through the center of the projection as straight lines.

This of projections is a very important issue, also:  in cartography
one must always do some trade off, because the Earth is round and all
that... Some projections keep distances, others forms, others areas,
and so on. Take for instance Mercator maps, the most usual ones,
which are very good when you must follow a constant bearing (they
appear as straight lines), but expand areas at high latitudes and
contract areas near the Equator.

The Mercator image of the world, centered on some peculiar fraction
of the imperialist Triad (North America, Western Europe, Japan) is
twice as misleading because areas placed North of the 40thN paralell
are outrageously enlarged (true, same happens with lands to the
.South of 40S, but there is very little land there). Compare
Greenland and, say, Brazil, on a Mercator map. See what I mean?

You can also try to get some useful map links from Oddens bookmarks
or 3G on W3: The Great Globe Gallery (I do not have the URLs handy,
sorry).
