GRIB routing

Firstly, this is the format in which files are saved when you create your
own forecasts using the
make Grid
function (see above).
Secondly, GRIBs will be automatically converted to this format if they
have been viewed in the
GRIB viewer
, in which case the file will have
been split up into sections of different data:
Current filename_c.cgf
Wave height filename_h.cgf
Temperature filename_t.cgf
Pressure filename_p.cgf
Wind filename_w.cgf
Thirdly, files are automatically converted to this format if you open and
then save them in the
GRIB.exe
program (see above).
GRIBS in Planning
Run Deckman in the normal way. Select
menu>planning>setup plan
and then
use GRIB wind forecast
and/or
use current GRIB
. Click on
wind file
or
current file
button and choose which GRIB file to use and
confirm by choosing
Open
. Remember the file must be in the form
readable by Deckman with the .cgf extension. Set up the rest of the plan
as you would normally—if necessary see page 3.14 for a reminder.
In the same way as it is advisable to input various different scenarios
into
What If?
and Planning, it is also possible to change the GRIB
forecasts as necessary. On longer passages, especially, this is a useful
function; for instance if you hear new weather information but can't
access updated GRIB files.
Editing GRIB data
By choosing the
edit GRIBs
icon (shown left) you can make some
changes to the GRIB files: offsetting the forecasts or changing the
timings for example. For any changes made here Deckman will
automatically update the Planning function, immediately showing you
the new set of isochrones.
