software for distribution-maps

Fri Nov 29 09:33:32 CST 2002

Hi!

Is there anyone out there who know about any compter program (for PC or Mac) that is particularily useful in constructing distribution-maps? I am 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)...

How do people make distribution-map these days?  I guess there are many different practices but I would be interested in knowing them all because I plan to draw some 1000 maps in the near future...
