C-Forecast
C-Forecast is an innovative meteorological forecasting system with the abil-
ity to visualise the weather forecast, for a given area, directly on to the area related
cartography on a chart plotter. The weather data is transferred very quickly to the
plotter thanks to C-COM, a device for data-transfer via GSM developed by C-MAP.
In order to access the C-Forecast it is necessary to set up a subscription. The
only other cost will be the GSM-call to the remote weather report server, normally
lasting less then a minute.
With C-Forecast it is possible to receive weather information regarding the
wind, speed and direction, as well as the height of the waves in the area. The weather
data will be superimposed on to the C-MAP NT
+
cartography and visualised directly
on the plotter screen.
In order to access the C-Forecast, the plotter must have the necessary soft-
ware to make the connection, through the GSM-modem (C-COM), with the weather
data server.
The area covered by the weather information is determined by either the
actual position and heading, given by the onboard GPS, or co-ordinates entered manu-
ally by the user. The user variable features can be pre-set through the C-Forecast
menu on the plotter (see Fig. A) together with the level of detail. To see the area
covered by the C-Forecast, please refer to the c-forecast.c-map.com web site.
The weather forecast is covering a period of 48-hours, within which the user
can collect the information for any period of 6 hours (example: at 2 PM on the 21
st
of
March 2002 a user's request a weather forecast, the forecast will cover the period for
the following 6 hours based on the predicted weather situation at the time of collec-
tion, ending at 8 PM on the 21
st
of March 2002). The weather information on the
C-Forecast server is revised every hour, covering the following 48 hours.
