Standard Metadata

Standardized metadata is critical to preserving the
usefulness of data over time

Standards provide a common set of terms

Ensure usability of data for communities that know and
understand the standards

Enables communities to archive, search and access
information easily
From Disparate Resources
to Standardized Content

Disparate resources of metadata are available for NESDIS
missions, satellites, sensors, and products

CLASS metadata gathers existing resources and organizes
the information in a standard way
Different Resources
Have Different…
  Organization of Information

  Terminology

  Intentions

  Content

  Resource Locations
      From Distinct and Different Resources
      to Standardized Content In One Location

Remote Sensing Extensions (RSE)

Define content standards for metadata that describe data
obtained from remote sensing activities

RSE are directly applicable to NOAA satellite products

Fulfill a need that was not addressed by the original FGDC
metadata content standards

Standardized CLASS Metadata is Good

It will benefit current and future communities

CLASS implementations of the FGDC Metadata is
cutting edge

 Feedback and support for the metadata content of
satellite data is highly encouraged
