proj4

Added by F Lapointe over 5 years ago

Hi,

While I was remapping a dataset with

cdo remapbil,CDO_proj ESL_-31000.nc ESL_-31000b.nc

I have got this error:

cdo remapbil (Abort): proj4 support not compiled in!

What is the meaning of such error, i.e module proj4 not loaded or other?
My data are attached with the remapping script.
Thanks

François

hi François!

The CDO binary can be built with support of several external libraries. Each of them enlarges the featureset of CDO, like netcdf output (libnetcdf), grib2 output (eccodes) , fast four transformation (fftw3) and some more

you can check, what your binary can do with 

cdo -V
On my machine this looks like
% cdo -V

PS: i will check your data with my CDO version

RE: proj4 - Added by Ralf Mueller over 5 years ago

your input file has time-dependent coordinates - CDO is not able to handle this. Even if I get rid of the time-dimention in the coordinates (since there is only a single timestep) by 

cdo --reduce_dim -copy ESL_-31000.nc t.nc
the coodinates do not seem to be correct
% cdo sinfov t.nc 
   File format : NetCDF
    -1 : Institut Source   T Steptype Levels Num    Points Num Dtype : Parameter name
     1 : unknown  unknown  c instant       1   1   1256561   1  F32  : delta_SL      
   Grid coordinates :
     1 : curvilinear              : points=1256561 (661x1901)
                              lon : -80 to 4.490262e+19 degreeN
                              lat : -1.595315 to 4.490262e+19 degreeE
   Vertical coordinates :
     1 : surface
lon : -80 to 4.490262e+19 degreeN doesn't seem right
