Hello All,
 
  Just spent about 15 minutes discussing how to classify digital
spatial data with someone in cataloging, and we have had no brilliant
insights.  Therefore, I am asking for comments from the list.  Please
address your comments to the list, as I am sure that others are
interested.  The problem:
 
We purchased some of the datasets available from the EROS Data Center
during the last year.  We have some AVHRR in the QKs (plant surveys);
another library has put some similar data in the QBs (meteorological
and climate change).  So far, LC has not cataloged these datasets.
 
I know that we have all complained long and hard about the
difficulties of .A4 for aerial photography.  NOW, to top that off, we
have data on CD-ROM that should really be cataloged somewhere in the
G Schedule, but no place to put it.  (I checked the new revisions for
the G schedule with no success).
 
Realistically, all spatial information, no matter the format, should
be classed with and according to the same classification schedule,
in other words, the G-schedule.  However, I think we need to revise
the G-schedule to make room for new formats.  Does anyone know if
there are plans for another subject class--one that could be used for
aerial photography and remotely sensed imagery?  Is it time for a new
class?
 
How are other libraries handling digital spatial data?  Linda
