Re: [ferret_users] memory problem with large file when regredding



Re,

Thank you Satyesh for your answer.

Unfortunatelly, my variable does not have a time dimension.
So spread the work into parts on L dimension won't help.
My variable is defined as follows:
dimensions:
        lon = 36000 ;
        lat = 18000 ;

If I  use JLIMITS then I get this error message:

save/clobber/file="($03)"/JLIMITS=1:300 mask
 !-> LIST/FORMAT=CDF/clobber/file="tyty.nc"/JLIMITS=1:300 mask
 LISTing to file tyty.nc
 **ERROR: invalid command: Does not encompass data to be written: JLIMITS=1:300
          Variable: MASK


The complete test is:

wget https://www.ngdc.noaa.gov/mgg/shorelines/data/gshhg/latest/gshhg-shp-2.3.7.zip
unzip gshhg-shp-2.3.7.zip
gdal_rasterize -a area -te -180 -90 180 90 -tr 0.01 0.01 i/GSHHS_i_L1.shp mask_i_L1_0.01.nc
---> Rasterize the vectors shorelines into a 0.01° gridded land/water variable (4.9Go).
