As someone who use to draw computer maps for a
living, it looks like they took the basic version of
ArcView (the leading GIS program), exported each state as
a graphic, then pasted it back together using
PhotoShop, which will explain the jagged borders. When you
call up an individual state, it will center the
projection on the center of the state. For example, the
KY/TN border was probably done with two different
projections. Even though I haven't done it in nearly three
years, something tells me with an hour of effort I could
do a much better job. Shrinking it to fit the screen
would be one thing.
Pride in your work always
shows. The lack of pride in your work always screams.
