Create a Routing in qtVlm by locating your boat icon somewhere and then placing a POI somewhere at your destination
Then you can create a box covering the entire sailing area holding down the right key of your mouse and moving it till the area is covered. Then goto the gribfile area and download the grib for the indicated area.
Click the Routings/create a routing and OK - the route
will start creating before your very eyes magically.
To transfer the route
or track data to OCPN,right click the route so the line increases itīs with and select copy route to kml.
Switch over to OCPN displaying the same area and right click either paste Route or paste Track. (or both) Your optimized route is now showing on your map.
Use the Route/Track Properties window (right clik the route) to view all details.
Hope this is helpful.
Thanks Sinbad, this got me started.
I would a couple of additional hints for useability:
1. When creating a routing check the Convert to Route box.
2. Then go to Route>Edit Route, select the route that you just created and check the simplify box(upper right) and OK This will remove lots of unnecessary way points. After pasting into Opencpn
you may want to remove more.
3. I really like the Route>Route Details screen
. It shows the detail of each leg including whether the motor
is running or not.
4. After creating a route, you can view the wind
conditions at any point/time along the route by pressing the right arrow in the tool bar (which advances the GRIB time). A small square will appear at your location for that time.
