Hello,
So, in the end, this is a matter of updating SATE_LON and STATE_LAT on
go/geo_borders.cdf and
go/geo_borders_intermed.nc
And sending them to someone at NOAA, if we wanted it to be shipped
with new versions of Ferret. Am I right? Would that be accepted if we
fixed (as long as we don't break everything else)?
Also, if we wanted like Otacilio asked, to draw a particular
country's state lines, essentially we can make a (for example)
go/land_brstates.jnl (for example for Brazil state borders), and have
it use the STATE_LON and STATE_LAT from a different file from which we
have only the brazillian state borders, so we have similar behavior of
go land and go land_detail. Of course, this is not something one would
expect to get inside the official ferret packages as it implies a new
script (which ONLY changes the data source for the STATE_* vars) plus
the said data file.
But if we think a little further, we can give the STATE_* variable
another dimension (the country) on the data files and choose either
all or an vector of desired country state borders to be drawn (on go
land[_detail] syntax -- additional script argument). This option could
be accepted by NOAA team to make it go live and at the same time
resolve the issue Otacilio has (and maybe others in the future). Or
would such a change (even though the default could be to write down
every state) is likely to be assumed "too overkill" to be elegible for
distribution in the official code?

Hi,
Have a look to this thread posted on the ferret mailling list.
http://www.pmel.noaa.gov/maillists/tmap/ferret_users/fu_2012/msg00051.html
It exposed a solution based on kml files that are available from
http://www.gadm.org/
at different admnistrative levels.

Hi -
There's an FAQ about coastlines and borders -
http://ferret.pmel.noaa.gov/Ferret/faq/detailed-coastlines-and-borders
which gives a couple of resources that we know of for coastline data.
It also discusses formatting the data for this kind of data.
Basically all you need is (lon,lat) data for the border and then plot
it with the PLOT/OVER/VS command.

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Two states of Brazil are with outdated borders (Goias/Tocantis and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,
