ISO 19115 Geographic Metadata Information
The Earth Science Division (ESD) Base Metadata Requirements document defines the ESD-approved implementation guidelines for required metadata to be included in science data products. The metadata requirements represented in this page provide a means of assuring the consistency of data requirements across subsystems, and supporting the data standardization necessary for system interoperability. The International Organization for Standardization (ISO) Geographic Information – Metadata standard 19115 (and related standards) shall be used to describe science data products. This standard includes two parts, 19115-1 and 19115-2. 19115-1 and 19115-2 include elements that are critical for NASA collections and products. In addition, the data quality elements of 19115 have been extracted into another standard (ISO 19157). Complete descriptions of NASA collections and products will require elements from all of these standards.
Missions will need to work with metadata specialists at their assigned DAACs to meet this requirement. At a minimum, the mission data system should provide enough information that the DAAC can generate sufficient collection level and granule level metadata to ingest into the Common Metadata Repository (CMR). ISO-compliant metadata can be exported from CMR as needed.
User resources for ISO metadata, CMR, and the Unified Metadata Model on which CMR is based are provided below. NASA conventions and best practices for ISO 19115 are currently under development, but a wealth of user resources is available.
NASA employees and those supporting NASA projects can obtain official ISO documentation at no cost, via the NASA Technical Standards Program. You will need a NASA Agency User ID and password to access the Standards site. For those who don't have an Agency User ID, please contact Christopher.S.Lynnes@nasa.gov
