software for distribution-maps

[Holger Kreft]

Dear Torbj?rn,
Esri?s ArcView offers a lot very usefull features for creating
distribution maps and especially for analyzing them. All your data
points are kept in a database which is connected to this Geographical
Information System. With the appropriate underlying information you can
query climate data, elevation etc. automatically with this program.
Unfortunately, it is not a very cheap programm, but on the other hand it
offer almost endless possibilities.

Holger.

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)...
