We present an overview of the ESDIS Standards Office (ESO). Information is provided about the ESO including an overview of the standards currently approved for use in NASA Earth Science Data Systems as well as standards and specifications currently under development. We also provide an overview of the ESO Standards Process. The ESO is also assisting the Common Metadata Repository (CMR) Systems Engineering Team with a series of reviews of metadata documents. Information about this is also provided. This poster is meant to provide an introduction to those unfamiliar with the ESO as well as to provide information for discussion with ESO Staff members who will be presenting the poster.
