Weather_routing_pi recompiled seems to be working ok now. Tested with older gribs and got it working, then tried new files downloaded using zygrib, some over Great Lakes
The newer zygrib files work for the most part, but there is one problem that shows up over the Great Lakes
which seems to be related to Land checking..
When "Detect Land" is checked the resultant Isochrones are confined to a small box.
When "Detect Land" is NOT checked the full route is calculated.
I note that both of these were done with Climatology "disabled".
When Climatology is "enabled" I see that there is no wind
data available from Climatology over the Great Lakes (there is other data available). Then plugin just calculates the route as is normal, provided the route is within the grib area.
Why the Boxed routing?
