Chapter 9 : Wind and current
forecasts
This chapter outlines the use of digital weather forecasts in Deckman.
Firstly, it discusses GRIB files. As was seen earlier (see page 3.14)
these can be used in Deckman's Planning calculations. This chapter will
discuss viewing the data from GRIB files in Deckman overlaid on a
chart, and also how they can be downloaded from a choice of two
sources from within Deckman. There are also notes on a couple of tools
which are supplied with Deckman to manipulate GRIB data.
The chapter will then discuss how you are able to 'draw' your own
forecasts within Deckman, which can then be used in the routing.
GRIB viewer
The GRIB viewer function allows you to import a GRIB file into
Deckman, and view the data overlaid onto a chart; there are also very
flexible functions to allow you to control the appearance of the GRIB.
To enter the GRIB viewer function select menu>view>GRIB view:
you will then be presented with a number of buttons along the bottom of
the Navigation screen (see Figure 9.1). To choose which GRIB file you
wish to import, click Select GRIB File (bottom left, though this may
display a file path if the function has been used previously), Find File
and then browse to the correct GRIB file, followed by Open. A series of
arrows will then be overlaid on your chart illustrating data from the
GRIB file (you may have to zoom to the area covered by the file) and
data will appear in some or all of the boxes at the bottom of the display
(depending on what data is in the GRIB file). The box to the left of
Select GRIB File allows you to choose which time you wish to see
displayed.
