[GRASS-user] Diffusion-based method for producing density-equalizing maps

[Martin Wegmann]

hello, 

these cartograms are not very important for a GIS but fancy and nice for a 
presentation, hence it would be great to have them implemented in GRASS (as 
add-on)

have a look at
http://www-personal.umich.edu/~mejn/cartograms/

the original paper can be found here:
http://www.pnas.org/cgi/content/abstract/101/20/7499

there does some code exist, but haven't found any licensing informations
