The optional Grib module lets you overlay weather forecasts to your charts, and plan your navigation accordingly, either manually, or in conjunction with the new Routing module available since version 17.0 of ScanNav. It also gives you access to the Grib download service located on ScanNav's or third parties servers.
The ScanNav Grib download service lets you select the model and type of data, the time steps, and define the geographic area directly from ScanNav. It manages forecasts issued from the following providers:
The Grib files can be downloaded directly using the http protocol, or by email requests. They are compressed so as to limit download times.
Starting with version 17.1, ScanNav interfaces with Great Circle, and allows you to download Grib files corresponding to your subscription directly from ScanNav.
Founded by passionate sailors and offshore racing skippers, Great-Circle specializes in producing high-resolution weather data. They are present on all the biggest races, and on board pleasure boats.
Access to other Grib providers such as SailAMail or SailDocs is also integrated directly from ScanNav
Notice: The GRIB module also lets you use any standard GRIB files (Grib V1 and/or V2) , whatever download source it comes from.
