Function Documentation

◆ misspack()

void misspack ( float *  fld,
g2int  ndpts,
g2int  idrsnum,
g2int idrstmpl,
unsigned char *  cpack,
g2int lcpack 
)

This function packs up a data field using a complex packing algorithm as defined in the GRIB2 documention.

It supports GRIB2 complex packing templates with or without spatial differences (See Template 5.2 and Template 5.3).

This function fills in GRIB2 Data Representation template arrays with the appropriate values.

Parameters
fldContains the data values to pack
ndptsThe number of data values in array fld
idrsnumData Representation Template number. Must equal 2 or 3.
idrstmplContains the array of values for Data Representation Template 5.2 or 5.3.
  • 0 Reference value - ignored on input, set by misspack routine.
  • 1 Binary Scale Factor - used on input.
  • 2 Decimal Scale Factor- used on input.
  • 6 Missing value management.
  • 7 Primary missing value.
  • 8 Secondary missing value.
  • 16 Order of Spatial Differencing (1 or 2).
cpackThe packed data field (character*1 array).
lcpacklength of packed field cpack.
