[ferret_users] "trim" a dataset

[Andy Jacobson <Andy.Jacobson@xxxxxxxx>]

Howdy,

I'm using a mask to cut out a contiguous region of data from a global  
dataset.  The result is a small blob of valid data sitting inside a  
vast global domain of missing data.  When I save the dataset, all the  
missing data are also written to disk, and I'd like to avoid that by  
defining the smallest rectangular region that contains my valid data.   
I'd then write out only that rectangle instead of the entire globe.   
Anybody know how to get the bounding latitude & longitude values to  
define this rectangle?

Thanks,

Andy
