Dear Otacilio Leandro,
Question 1:
I was thinking if its possible to draw the lines of states only at Brazil.
The easiest way would be to obtain a border dataset somewhere from the
Brazilian government. The data must be available digitally,
somewhere. Convert it to netcdf or load it directly from ASCII, and
plot it the same way as the "go land" script does.
Question 2:
Two states of Brazil are with outdated borders (Goias/Tocantis and Mato
Grosso/Mato Grosso do Sul). Is there any way to get the go land_detail
script file with update borders?
Same answer really: you'll have to find an up-to-date border data
set. The government website would probably be the first stop to
visit.
Kind regards,
Hein Zelle
