Re: LAS/LIS User Interface

[Jonathan Callahan <Jonathan.S.Callahan@xxxxxxxx>]

Joe,

As we are recommending GDS as a solution for folks with GRIB data and/or
temporally aggregated data it would nice to include your scripts as part of
the LAS distribution.  Perhaps the best way to start would be for you to
announce the availability of your scripts on the las users email list.  Your
email is currently buried in a thread and a title like "*** Announcing
GDS-LAS utility scripts ***" would be easier to spot.  Then I'd like to
include them in the 'contrib/' area of the LAS source code.  By (my own
personal) definition, items in the 'contrib/' area essentially alpha code
that we are putting out there for people to test.

I'm aware of several folks who are currently installing GDS and any GDS-LAS
utilities you have would be put to use right away.

Cheers,


-- Jon
