Dear list,
Sorry for a GRASS non related question. Does anybody know a software in which
one could make cartograms where the area of the polygon reflects the size of
the variable in question. E.g. in a map of the countries of the world
(projection should be equivalent of course), the area of the country shows the
size of the population of the country, not the actual area. I would be happy
with either contiguous polygons with distortion of the shape or non contiguous
polygons without shape distortion.
If you fell responding to the question would burden the listers with non
related topics, please reply me off list.
Thanks,
Miha

Cool Link! It looks like the underlying algorithm is written in C, and open
source. Compiles nicely on linux -- although it requires an ESRI ungenerate
format file as input... and v.out.arc seems to be stranded in GRASS54.

Another limitation of that C algorithm for cartograms is it only
outputs .ps files.
Try the link to the Java version.
(http://people.cas.sc.edu/hardistf/cartograms/) It inputs/outputs
shapefiles and has a nice GUI that autmates alot of the tediousness of
the C version.

Actually,
It will output an UNGENERATE format vector file too.

Ahh good to know. You mentioned old versions of GRASS could deal with
this format...Are there any open source tools than work with the
UNGENERATE format?

Looks like there is!

Perhaps someone would like to write-up how to tie all three things :
GRASS-cartogram-gen2shp for the GRASS newsletter... ?
