Statistics for the site are are extracted from the
web-server logs by a custom script, then the
ISO 3166 2-letter country codes for the IP address are found using
maxmind's
free
GeoIP country database.
Only one download of each file is counted for each IP address, and I have
excluded from the totals any IP address downloading more than 300
palettes; These are usually spiders too dozy to read
robots.txt.
The maps produced with these statistics are mostly standard
GMT scripting, apart from the painting of the countries: For this
I have a
script
which maps the ISO 3166 codes to files in the
mobilegraphics
state boundaries collection, used as input for psxy.
