Do you have an Almean world map in equirectangular format (ie., using the longitudes and latitudes as a cartesian coordinate grid) as well as in the sinusoidal projection shown on the Drilldown page?
(I've tried to convert the sliced-up sinusoidal projection into an equirectangular map, but the result doesn't look very good )
Not a current one, I'm afraid. I have one in progress, though in fact I'd forgotten about it for a few months. (I have no easy procedure for making it, by the way. I go cell by cell, distorting it to the right shape and redrawing it.)
What I did was to take the interrupted sinusoidal map and expand the map sections of each pixel line to fill the entire width of the map, but the polar regions - well, anything between the poles and the 45th parallells, really - looks rather iffy...
