----------------------------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
