Element Description
The Orbit Calculated Spatial Domains element describes the characteristics of the orbit of the tool used to provide or acquire the data for the granule.
Best Practices
The Orbit Calculated Spatial Domains element is optional and contains five sub-elements.
Orbital Model Name: The name / label of the orbital model.
Begin Orbit Number: The value of the beginning orbit used for data collection.
End Orbit Number: The value of the ending orbit used for data collection.
Equator Crossing Longitude: The longitude of the tool at the point when it crossed the Equator during data collection.
Equator Crossing Date Time: The date and time that the tool crossed the Equator during data collection.

Metadata Validation and QA/QC
All metadata entering the CMR goes through the below process to ensure metadata quality requirements are met. All records undergo CMR validation before entering the system. The process of QA/QC is slightly different for NASA and non-NASA data providers. Non-NASA providers include interagency and international data providers and are referred to as the International Directory Network (IDN).
