----------------------------Original message---------------------------- 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 = ....... According to Linda Zellmer: . . ----------------------------Original message---------------------------- . 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 . Zellmer, University of Wyoming . Matthew Gilmore [log in to unmask] D.C.
