ArcGIS is one program that I have used to make the dot maps before.  Sadly, when I changed jobs I had to leave my copy behind.  :(

Hi all,

I was wondering what software people use to make all those really clean dot-distribution maps I see in publications (e.g. the MONA series)?  It looks like you can select exactly the geographic region of interest anywhere in the world on the base map and then apply the data. Looks like you can also choose political boundaries, rivers, etc. How is the data applied? Does the software exist for Mac OS  We have GIS capability here but it takes a long time to become proficient and many of the map layers are not needed.
TIA for any help and best regards,  Richard
