March 23, 1999 GOIN 99, Honolulu, HI 2 Introduction zInter-institutional collaborations are awkward between observational scientists. zTraditional techniques for remote collaborations regarding in situ data are inflexible and static. zWeb technologies combined with Java present new opportunities for collaboration.

March 23, 1999 GOIN 99, Honolulu, HI 3 Design Goals zProvide a interactive and collaborative environment for in situ data exploration. zAllow co-plotting of profile data from multiple geographically distributed archives. zAllow profile data from local files (netCDF) to be read. zEnable scientists to interactively annotate data. yHighlight individual profiles yadd text, arrows, lines, etc zEnable scientists to interact with the data. yQuery values yQuery metadata (geographic location, etc.)

March 23, 1999 GOIN 99, Honolulu, HI 4 Approach Leverage (borrow) heavily from existing development efforts zHabanero, distributed interpersonal communications utilizing multi-user, collaborative work environments. zNOAAServer, a project whose purpose is to present to users a centralized and unified view of NOAA’s environmental information databases.

March 23, 1999 GOIN 99, Honolulu, HI 5 NOAAServer zProvides a mechanism to locate datasets distributed over many servers (NOAA wide). zUses an object oriented data model and CORBA/IIOP implementation of data access. zJava Graphics for display of in situ data.  More information at:
