I wrongly impllied that the sinusoidal is good on directions and route
distances. It holds its own as a world map because interruption is accepted
for world maps. But no one wants an interrupted map of a country, province
Because it concentrates its distortion in the corners, and because it's an
equatorially centered, rather than locally centered, projection, the
sinusoidal won't do well compared to other projections when it isn't
interrupted. And its directions and route distances aren't easily
But then I'd use a different map for directions and route distances.
Two things that can't be gotten from a different map are the depictions of
the data zones. Their position and their area (if you want areas). The
directions and route distances can be gotten from other maps.
