Gee, maybe I am missing something but couldn't you just class it as if it
were on paper?  Using the G Schedule.
That's what we do with microfilm/microfiche.
And it seems to me you still have the different "formats"--
aerial photo=GIF file,
topo map = .......

. 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
