The Spatial Information element stores information about the reference frame from which horizontal and vertical spatial domains are measured. The horizontal reference frame includes fields for Geodetic Model, Geographic Coordinates, and Local Coordinates. The Vertical reference frame includes fields for altitudes (elevations) and depths.
Providing Spatial Information is optional, but encouraged. This element can be used to provide horizontal and/or vertical coordinate system information.
The Spatial Coverage Type field is required for Spatial Information.
Spatial Coverage Type: Denotes the type of spatial coverage of the collection. While this field is not currently controlled, recommend providing one of the spatial coverage type enumeration values: EARTH/GLOBAL, HORIZONTAL, VERTICAL, ORBITAL, HORIZONTAL_VERTICAL, ORBITAL_VERTICAL, HORIZONTAL_ORBITAL, HORIZONTAL_VERTICAL_ORBITAL, LUNAR
Vertical Spatial Information
The following sub-elements can be used to describe Vertical Coordinate Systems.
There are 2 categories for Vertical Coordinate Systems including:
(1) Altitude System Definition
Altitude System Definition should be used to describe data with a vertical component that is above-ground. Sub-elements under Altitude System Definition are summarized below:
(2) Depth System Definition
Depth System Definition should be used to describe data with a vertical component that is below-ground. Sub-elements under Depth System Definition are summarized below:

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).
Please see the expandable sections below for flowchart details.

ARC Automated Checks ARC uses the pyQuARC library for automated metadata checks. Please see the pyQuARC GitHub for more information. |
DIF 10Providing Spatial_Info is optional in DIF 10 (Cardinality: 0..1). Note: There are no Vertical Coordinate System fields in DIF 10 - vertical information can be provided in the Vertical_Spatial_Info element. For details on Vertical_Spatial_Info please see the Spatial Extent wiki page. DIF 10 also supports an element called Data_Resolution which does not currently map to the UMM, however, there are plans to support it in the future.
