subsetting bbox

Added by Jay Su almost 5 years ago

Hello,

When we subset a file with a bounding box, there has to be at least one grid point inside. Is it possible to go to the nearest if no grid point is inside?

I am trying v1.9.7 to do something like point subsetting.

Thanks,
Jay

Hi Jay,

if you know that there is no grid point in your selected lonlat box and you know the center point location you can use e.g.

cdo -remapycon,lon=23.45632/lat=89.000452 infile outfile

to get the data of the nearest point.

Thank you Karin,

Unfortunately I dont know if there is a grid point in the bbox. And the grid sizes vary a lot, from 5 degree to 0.1 degree.

Is it possible in CDO that when sellonlatbox finds bbox is too small, it automatically calls lon/lat?

No, not in my opinion.
