Introduction

Section 3 contains the grid definition template (GDT) and the -gdt option prints the parameters used to define the grid as used by g2clib/g2lib (NCEP libraries). This option is only useful finding the grid parameters for later use by g2clib/g2lib.

The -gdt option will only work if g2clib is installed at compile time.

Usage

-gdt

Example
