dinates and is similar to plane charts of the 16th century. Mark Monmonier flatly
states, “If any projection is worth denouncing, it’s the vaguely named ‘geographical
projection’ popular among users of geographic information system (GIS) software”
(Monmonier, 2004, p. 176). On the map shown, one can see that the map enlarges
the northern states of the United States; this is because, like other rectangular projec-
tions, the meridians do not converge at the poles.
Other examples of the misuse of projections abound and yet should not happen.
There is little excuse for ignorance given the number of readily available tables of pro-
jection use, and no excuse for negligence or laziness. Using an unsuitable projection
because it was the most readily available base map is not acceptable.
