please let's do not complicate things:
Originally, grib-pi interpolated always even if it was not necessary ( when "interpolation is not set or when using next and previous buttons).
Off course if it was not necessary, the interpolation had no effect.
But with the 'moving grib" files and with files with no constant resolution, this not needed interpolation is not accepted. So a test was added in the function to eliminate it)
Unfortunately, Sean said that this test destroyed the weather routing activity and proposed to eliminate it.
I did it, sorry without sufficient thinking, so the current
Git (3.3.1710) should allow weather routing to work.
But the result is that moving gribs and no constant resulution grib no longer work.
Has any body tested weather routing with current
Git ? It should confirm Sean's statement.
To fix the problem in both plugins I proposed another patch above.
Could Sean answer if it suits weather routing? in this case we can close the case
Or could someone post a weather routing.dll compiled on current Git I can test myself (sorry I have no time to search how to compile it )
