Noaaserver

NOAAServer

  • Objective: Provide centralized, unified access to distributed NOAA data

  • Participants: All of the NOAA Line Offices

    • National Environmental Satellite Data and Information Service

    • National Marine Fisheries Service

    • National Ocean Service

    • National Weather Service

    • Oceanic and Atmospheric Research


Noaaserver1

NOAAServer

  • Initiated in NOAA’s Environmental Services Data and Information Management (ESDIM) office in 1995

  • Integrates 14 distributed data servers

  • Over 15,000 metadata descriptions

  • Available from the NOAA Home Page

    • http://www.noaa.gov

    • http://www.esdim.noaa.gov/NOAAServer

Operational NOAAServer

  • Locating data:

    • Enter search criteria

    • The NOAAServer returns a list of data collections meeting the search criteria

    • View a description of the data collection

    • If data is on-line, interact to subset data, obtain plot or listing of data

    • If sub-setted data is sufficiently small, data can be downloaded to the users disk


Operational noaaserver1

Operational NOAAServer*

  • Representative data:

    • satellite images

    • time series of oceanographic and meteorological station measurements

    • two-dimensional oceanic parameters

    • text documents

    • vertical profiles of measurements through the atmosphere and the ocean

Operational noaaserver4

Operational NOAAServer

  • Integrates NOAA Data and Information Services on the Web

  • Centralized search for NOAA wide data holdings:

    • Search, view, download/order distributed NOAA data

    • http and conventional, legacy CGI scripts

  • but different datasets have different navigation and interface characteristics


Where are we headed

Where are we headed?

  • Recent developments include methods for providing a centralized and unified data access

  • Next Generation NOAAServer

    • Data is easily located and accessed

    • User sees a consistent search and navigation interface

    • So data is viewed consistently across servers

    • Better service to a wider audience


Next generation noaaserver prototype demonstration

Next Generation NOAAServerPrototype demonstration

  • connects 6 geographically distributed data servers in Silver Spring, Boulder, Seattle

  • CORBA for network connections

  • unified interactive Java graphics*

  • data from distributed servers are co-plotted together on the same axis on the users desktop
