+---- Thread: GRIB weather forecasts (/thread-1141.html)
- GPSNavX - June 15, 2010
iNavX can request, download and display GRIB weather forecasts.
GRIB are output files generated by computer forecasting models. They are tremendously more compact than regular weather charts and because of their size are very well suited for download via wireless means. The largest producer of GRIB weather is NOAA although other organizations such as the military and research institutions also generate GRIB files. NOAA GRIB files are the best ones suited for marine forecasts.
GRIB files can come into iNavX three ways: X-Traverse or Email or iTunes:
Via X-Traverse
1) From the iNavX main menu, select "Setup".
2) Select "X-Traverse Account".
3) Enter email address used for X-Traverse account and X-Traverse password. Note if you forgot them, then reset password..

5) Select the "Forecast" tab.
6) Select "GRIB Parameters".
7) Select "Request Via" and set to "X-Trav".
8) Select "Request GRIB".
9) Select the type of forecast desired.
10) In approximately one minute, select "Import GRIB".
11) If available, the newly requested GRIB will be in the menu ready for selection.
12) Select the local forecast date/time to display. iNavX will open the chart (a smaller scale chart may be loaded) to the GRIB.
13) Pinch to zoom in and out. Keep in mind that GRIB data is on 1/2 degree increments so zooming out may be needed.
14) Use the [<<] and [>>] buttons or tap the date/time to select a different local date/time.
15) Return to Forecast tab and select GRIB (bold font) and select "None" to turn off display of GRIB.
Note: Recommend logging on to X-Traverse.com account. Select "Settings" and enabling "Forward GRIB Notifications". This will send an email when a requested GRIB file is available. The GRIB can also be used in GRIB viewing software such as MacENC.
