//
|
|
// ABSTRACT: This Fortran Module contains info on all the available
|
|
// GRIB2 Data Representation Templates used in Section 5 (DRS).
|
|
// The information decribing each template is stored in the
|
|
// drstemplate structure defined below.
|
|
//
|
|
// Each Template has three parts: The number of entries in the template
|
|
// (mapdrslen); A map of the template (mapdrs), which contains the
|
|
// number of octets in which to pack each of the template values; and
|
|
// a logical value (needext) that indicates whether the Template needs
|
|
// to be extended. In some cases the number of entries in a template
|
|
// can vary depending upon values specified in the "static" part of
|
|
// the template. ( See Template 5.1 as an example )
|
|
//
|
|
// NOTE: Array mapdrs contains the number of octets in which the
|
|
// corresponding template values will be stored. A negative value in
|
|
// mapdrs is used to indicate that the corresponding template entry can
|
|
// contain negative values. This information is used later when packing
|
|
// (or unpacking) the template data values. Negative data values in GRIB
|
|
// are stored with the left most bit set to one, and a negative number
|
|
// of octets value in mapdrs[] indicates that this possibility should
|
|
// be considered. The number of octets used to store the data value
|
|
// in this case would be the absolute value of the negative value in
|
|
// mapdrs[].
