software for distribution-maps

[Guy Nesom]

What about a digital map that shows only USA state outlines and county
outlines within each state?  Something onto which various symbols could be
overlaid.

used to doing this by scanning a suitable background-map and drawing dots on
it by a conventional drawing program. When I have geographical coordinates
(which is far from always the case) I have tried to use a calculation
program to make a scatter-plot with dots that can be superimposed on my
scanned map, but this only works on a map-projection with right angels (i.e.
assuming a flat earth)...

plan to draw some 1000 maps in the near future...
