Positions in a Subset

Positions in a Subset

For obtaining positions in a subset the function GDSPOS is used in GIPSY. It decodes the user input into grid positions, which are returned in a double precision array.

Note that the positions returned by GDSPOS should be converted to integers before using it for calculating coordinate words etc. In this case the nearest integer must be taken, i.e. with the function NINT.
