Dear LAS mailing list,
I'm wondering how subsetting curvilinear plots in LAS works.
Particularly, if the LAS selection box exceeds the bounds of the
regridded curvilinear domain, what formula does Ferret use to
transform the "out of bounds" coordinates to the proper values for
Ferret's internal use?
Attached are some screenshots to show an example. On [screen_1.png],
I've done a rubberband selection on the mini-map with the lower-left
portion being outside the dataset domain. On [screen_2.png], you can
clearly see that the "out of bounds" area has been properly adjusted
to be within the domain. Kindly take note that this is a curvilinear
dataset.
In addition, if I make a rubberband selection, does Ferret regrid the
entire domain first and then subset from there, or does LAS pass the
selection lon/lat coordinates to Ferret and Ferret transforms the
coordinates to the x/y equivalent in order to subset the curvilinear
dataset before regridding? Any information is greatly appreciated.
