Description

Creates an empty convection map file from a grid file.

The file created is written to standard output.

The output is in the map file format but most of the data fields are empty. Subsequent processing is required to add such things as the IMF data, Model vectors and coefficients of the spherical harmonic fit.

Examples
map_grd -l 60 -vb 19981020.grd > 19981020.map

Creates an empty map file from the grid file called "19981020.grd". The lower latitude limit is set to 60 degrees. The file created is called "19981020.map" and status is logged to standard error.
