Element Description

The Spatial Extent element describes the geographic coverage of the data. For data collections, the spatial extent describes the area of the Earth that the collection covers. For specific files or granules, the spatial extent describes the area covered by that individual file. 

The Spatial Extent element may also be used to describe vertical coverage of the data and orbital parameters where appropriate. 

The Spatial Extent's coordinate system and resolution is also included under this main element. The horizontal spatial domain includes the geographic coverage of the data plus its coordinate system and the geographic coverage's resolution. This information provides the reference frame from which horizontal and vertical spatial domains are measured. The horizontal reference frame includes fields for Geodetic Model, Horizontal Data Resolution, and Local Coordinates. The geographic coverage's resolution is defined as the smallest horizontal distance between successive elements of data in a dataset. This is synonymous with terms such as ground sample distance, sample spacing and pixel size. It is to be noted that the horizontal data resolution could be different in the two horizontal dimensions. Also, it is different from the spatial resolution of an instrument, which is the minimum distance between points that an instrument can see as distinct.

Best Practices

In the CMR, there is the option to describe the horizontal, vertical, and orbital spatial coverage of a dataset along with its coordinate system and resolution. The type of spatial coverage being described in the metadata is identified via the 'Spatial Coverage Type' metadata element. There are five different controlled vocabulary options for 'Spatial Coverage Type'. These include:

  • Horizontal
  • Vertical
  • Orbital
  • Horizontal and Vertical
  • Orbital and Vertical  

Each spatial extent type requires different information. The information needed for each type is summarized below: 

Horizontal 

Horizontal spatial extent refers to data covering the surface of the Earth. For horizontal spatial extent, a coordinate system must be specified with the choice of either a Cartesian or Geodetic coordinate system:

SpatialExtent/HorizontalSpatialDomain/Geometry/CoordinateSystem:

Choice of:

  • CARTESIAN   
  • GEODETIC

Please see the Coordinate Systems section of the CMR Data Partner User Guide for instructions on how to assign the appropriate coordinate system.

Furthermore, there are four different options for describing horizontal spatial coverage. Only one of these options may be selected, however, the selected option may be repeated as many times as necessary (e.g. you can't provide a bounding rectangle and a point, but you can provide multiple bounding rectangles). The four options are:

(1) Point

    • A point location defined by a latitude and longitude coordinate. Multiple points may be provided if necessary.

(2) Bounding Rectangle

    • A rectangle defined by a north latitude coordinate, south latitude coordinate, east longitude coordinate, and west longitude coordinate. The north bounding latitude may not exceed 90 degrees, the south bounding coordinate may not be less than -90 degrees, the west bounding coordinate may not be less than -180 degrees, and the east bounding coordinate may not exceed 180 degrees. 

(3) GPolygon

    • A polygon defined by latitude/longitude point pairs. The more points are provided, the more detailed the polygon will be. Exclusion zones within the polygon can also be identified. Please see the CMR Data Partner User Guide for more details. 

(4) Line

    • A width-less line defined by latitude/longitude point pairs. Multiple points may be provided to express a complex line. Please see the CMR Data Partner User Guide for more details.

Horizontal Resolution and Coordinate System

The following sub-elements can be used to describe Horizontal Resolution and Coordinate System.

There are 3 categories for Horizontal Resolution and Coordinate System Data Resolution including:

(1) Geodetic Model

Geodetic Model is used to describe data that has been georeferenced to a datum, which is a well defined ellipsoidal/spherical representation of the Earth. There are many different standard datums. Knowing which datum the data is encoded in is extremely useful for manipulating the data using GIS software. Sub-elements under Geodetic Model are summarized below:

  • Horizontal Datum Name: The name of the datum the data are encoded in. Also commonly referred to as a geodetic datum. A geodetic datum is a more localized/ specialized version of a simple Ellipsoid model of the Earth (see below). It is recommended that EPSG Datum names be used. 
  • Ellipsoid Name: An elliptical or spherical shape representing the Earth. An Ellipsoid's shape can be defined by a major axis (longer axis) and a minor axis (shorter axis). There are standard names for different Ellipsoids - it is recommended that EPSG Ellipsoid names be used. 
  • Semi Major Axis: The radius of the major axis of the Ellipsoid. The length and units of the Semi Major Axis should be defined in the Ellipsoid standard. 
  • Denominator Of Flattening Ratio: The ratio of the Ellipsoid's major axis to the difference between the major and the minor axis. Also referred to as the Inverse Flattening ratio. The smaller the ratio, the 'flatter' or more oval-like the Ellipsoid's shape will be. The units of the Inverse Flattening ratio are also defined by the Ellipsoid standard. 

(2) Horizontal Data Resolution

Data that has been georeferenced to a geodetic datum can have resolution information. There are three basic types of spatial coverages: Point Data, Non Gridded Data, and Gridded Data. Depending on which type different set of data is useful to describe the data sets resolution. These are summarized below:

  • Varies Resolution: The data product's resolution information is varied and not described in the data set's metadata record. For more information the data set's landing pages should be visited.
  • Point Resolution: The data product's spatial extent is a point and therefore there is no resolution information to describe.
  • Non Gridded Resolutions: The data product's spatial extent is not gridded and the following set of sub elements apply:

    • XDimension: The resolution value on an X axis on a plane - On the Earth this is normally the Longitudinal axis.
    • YDimension: The resolution value on a Y axis on a plane - On the Earth this is normally the Latitudinal axis.
    • Unit: The unit of measure for the X and Y dimensions. The valid values are controlled and they include: Decimal Degrees, Kilometers, and Meters.
    • ViewingAngleType: Describes the sensors angle when the measurements are taken. The valid values are controlled and they include: At Nadir and Scan Extremes.
    • ScanDirection: Describes the direction that is scanned by the sensor. The valid values are controlled and they include: Along Track and Cross Track.
  • Non Gridded Range Resolutions: Resolution ranges are necessary for data that is collected by aircraft and other such vessels. The following set of sub elements apply to describing the data product's resolution:

    • MinimumXDimension: The minimum resolution value on an X axis on a plane - On the Earth this is normally the Longitudinal axis.
    • MinimumYDimension: The minimum resolution value on a Y axis on a plane - On the Earth this is normally the Latitudinal axis.
    • MaximumXDimension: The maximum resolution value on an X axis on a plane - On the Earth this is normally the Longitudinal axis.
    • MaximumYDimension: The maximum resolution value on a Y axis on a plane - On the Earth this is normally the Latitudinal axis.
    • Unit: The unit of measure for the X and Y dimensions. The valid values are controlled and they include: Decimal Degrees, Kilometers, and Meters.
    • ViewingAngleType: Describes the sensors angle when the measurements are taken. The valid values are controlled and they include: At Nadir and Scan Extremes.
    • ScanDirection: Describes the direction that is scanned by the sensor. The valid values are controlled and they include: Along Track and Cross Track.
  • Gridded Resolutions: The data product's spatial extent is gridded and the following set of sub elements apply:

    • XDimension: The resolution value on an X axis on a plane - On the Earth this is normally the Longitudinal axis.

    • YDimension: The resolution value on a Y axis on a plane - On the Earth this is normally the Latitudinal axis.

    • Unit: The unit of measure for the X and Y dimensions. The valid values are controlled and they include: Decimal Degrees, Kilometers, and Meters.

  • Gridded Range Resolutions: Resolution ranges are necessary for data that is collected by aircraft and other such vessels. The following set of sub elements apply to describing the data product's resolution:

    • MinimumXDimension: The minimum resolution value on an X axis on a plane - On the Earth this is normally the Longitudinal axis.

    • MinimumYDimension: The minimum resolution value on a Y axis on a plane - On the Earth this is normally the Latitudinal axis.

    • MaximumXDimension: The maximum resolution value on an X axis on a plane - On the Earth this is normally the Longitudinal axis.

    • MaximumYDimension: The maximum resolution value on a Y axis on a plane - On the Earth this is normally the Latitudinal axis.

    • Unit: The unit of measure for the X and Y dimensions. The valid values are controlled and they include: Decimal Degrees, Kilometers, and Meters.

  • Generic Resolutions: The data product's spatial extent is not known if it is gridded or not.  The following set of sub elements apply:

    • XDimension: The resolution value on an X axis on a plane - On the Earth this is normally the Longitudinal axis.

    • YDimension: The resolution value on a Y axis on a plane - On the Earth this is normally the Latitudinal axis.

    • Unit: The unit of measure for the X and Y dimensions. The valid values are controlled and they include: Decimal Degrees, Kilometers, and Meters.

(3) Local Coordinate System

Data collected over small or localized areas may be georeferenced to a custom or highly specialized reference system. In order to accurately compare the local data to other data, the local coordinates must be converted to a standard reference system such as one of the EPSG geodetic datums. The Local Coordinate System fields provide information about the local coordinate system. Sub-elements under Local Coordinate System are summarized below:

      • Geo Reference Information: Information on how the local system were registered to a standard reference system (e.g. control points, satellite ephemeral data, and inertial navigation data). In some cases, the user may be responsible for georeferencing the data.
      • Description: A description of the Local Coordinate System and georeference information.

A Description sub element is included in the ResolutionAndCoordinateSystem element that allows a CMR data provider to explain to a user the data products horizontal coordinate system and resolution.

Providing the horizontal coverage's resolution and coordinate system data is optional, but encouraged and is used to provide horizontal and/or vertical coordinate system information.

Vertical

Vertical spatial domain can be used to describe the coverage of data with a vertical component. The type of vertical coverage being described in the metadata is identified via the 'Vertical Spatial Domain/Type' metadata element. There are five different controlled vocabulary options for 'Vertical Spatial Domain/Type' in UMM-Common. These include:

SpatialExtent/VerticalSpatialDomain/Type:

Choice of:

  • Atmosphere Layer
  • Maximum Altitude
  • Minimum Altitude
  • Maximum Depth
  • Minimum Depth

Once a Type is selected, an accompanying value in the SpatialExtent/VerticalSpatialDomain/Value field must also be provided. For example, if "Maximum Altitude" was selected as the Type, the corresponding Value could be "50 KM."

Orbital 

When data is collected via a satellite, the Orbit Parameters metadata elements may be used to describe the spatial coverage. Please see the CMR Data Partner User Guide for additional details on how Orbit Parameters are used by the backtrack search algorithm for conducting spatial searches. Orbit Parameters includes the following sub-elements:

Swath Width: The width of the strip of the Earth's surface from which geospatial data are collected by a satellite, in kilometers. Only a number should be provided since the unit of kilometers is implied. If providing orbit parameters, Swath Width is required.  

Period: The time it takes a satellite to complete one complete orbit around the Earth, in decimal minutes. Only a number should be provided since the unit of decimal minutes is implied. If providing orbit parameters, Period is required.  

Inclination Angle: The angle between the equatorial plane of the Earth and the orbital plane of a satellite, in degrees. Only a number should be provided since the unit of degrees is implied. If providing orbit parameters, Inclination Angle is required.

Number of Orbits: "Indicates the number of orbits." 

Start Circular Latitude: "The latitude start of the orbit relative to the equator. This is used by the backtrack search algorithm to treat the orbit as if it starts from the specified latitude. This is optional and will default to 0 if not specified."   

Furthermore, the Granule Spatial Representation element is a required element. This element identifies how the spatial extent is expressed in the granule metadata associated with a collection. The spatial representation used in the collection metadata can be different than what is used in the granule metadata. Granule Spatial Representation is a controlled vocabulary field in the UMM-Common schema and includes the following options: 

  • CARTESIAN
  • GEODETIC
  • ORBIT
  • NO_SPATIAL

The granule spatial representation selected at the collection level must be utilized by the granules. Please see the Collection & Granule Spatial Relationships section of the CMR Data Partner User Guide for additional details.

The spatial extent of the granules should always fall within the spatial extent specified in the collection level metadata (and vice versa). It is the responsibility of the metadata author to ensure that collection-granule spatial relationships are compatible.

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).

    • Two vertices will be connected with a straight line.
  • General validation rules for geodetic coordinates
    • The implemented Geodetic model uses the great circle distance to connect two vertices for constructing a polygon area or line. If there is not enough density (that is, the number of points) for a set of vertices, then the line or the polygon area might be misinterpreted or the metadata might be considered invalid.

    • Any single spatial area may not cover more than one half of the earth.
  • General collection level rules
    • Each collection may specify only one coordinate system for its spatial coverage.
    • Each collection‘s coordinate system is independent of all other collections.
    • Each collection‘s coordinate system is independent of its granule spatial representation — i.e., a collection‘s spatial extent may be expressed in the Cartesian geometry, but have all of it‘s granules specify their spatial extents in the Geodetic geometry.
    • A collection specifies its granules‘ spatial representation, which cannot be overridden by a granule. This element is called GranuleSpatialRepresentation.
    • A collection with an orbital granule spatial representation must specify exact orbit parameters in order to facilitate granule discovery via spatial constraints.

    • Ingest for a metadata record will fail if any spatial metadata input is invalid with respect to the associate rules of the utilized coordinate system.

    • For any granules that are ingested for the collection, the granules spatial extent must exist within the collection's spatial extent.
  • The sub element GranuleSpatialRepresentation is required and so it must exist and must be filled in with one of the following enumerations: CARTESIAN, GEODETIC, ORBIT, or NO_SPATIAL. If the collection has granules associated with it the GranuleSpatialRepresentation cannot be changed.If SpatialCoverageType exists, it must be populated with one of the following enumerations: HORIZONTAL, VERTICAL, ORBITAL, HORIZONTAL_VERTICAL, ORBITAL_VERTICAL

  • Under HorizontalSpatialDomain
    • the geometry sub element must exist
    • if populated, the zone identifier must have at least 1 character and no more than 80 characters in length
    • In geometry
      • The coordinate system sub element must exist and be populated with one of the following enumerations: CARTESIAN or GEODETIC.
      • At least one of the geometry types (points, bounding rectangles, gpolygons, or lines) must exist.
      • For Point and Bounding Rectangle types all sub elements are required.
      • For GPolygon types

          • A polygon‘s vertices must be stored in order of vertex connection.
          • Provide the vertices in clockwise order. (If using ISO 19115-2 MENDS, the expected order is counter-clockwise and the CMR will convert the order to clockwise as it translates the record to UMM).
          • No consecutive vertices may have the same latitude and longitude, that is, no repeating points.
          • Polygonal lines may not cross each other within the polygon.
          • The first point and last point must be the same.
          • No polygon should cover more than half the Earth in the Geodetic coordinate system.
        • If the ExclusiveZone is used the Boundary sub element must exist.

ARC Priority Matrix

Priority CategorizationJustification

Red = High Priority Finding

This element is categorized as highest priority when:

  • No Spatial Extent is provided.
  • The Spatial Extent of the granule metadata falls over 1.0 decimal degree outside of the Spatial Extent specified in the collection level metadata.
  • The Spatial Extent appears to be inaccurate compared to the described data.
  • The Spatial Data Resolution or Datum information provided appears to be inaccurate compared to the described data.

Yellow = Medium Priority Finding

This element is categorized as medium priority when:

  • No Horizontal Data Resolution information is provided.
  • The Spatial Extent of the granule metadata falls outside of the Spatial Extent specified in the collection level metadata, but the difference is less than 1.0 decimal degree.
  • A recommendation is made to update the Spatial Extent to a form that more accurately reflects the data (e.g. providing 'Point' coordinates rather than a 'Bounding Rectangle' for point location data).

Blue = Low Priority Finding

This element is categorized as low priority when:

  • No Horizontal Datum Name is provided, if appropriate for the data.

Green = No Findings/Issues

The element is provided and follows all applicable criteria specified in the best practices section above.

UMM Migration

The translation between the operational version of UMM-C 1.13 and the UMM-C 1.14 is almost a one to one mapping. Since the old model doesn't have the descriptions, they can't be translated back or forth. The Horizontal Resolution and Coordinate System information has been moved to be co-located with the horizontal spatial extent information. Translating from the proposed UMM-C back to UMM-C version 1.13 the lower resolution will be used. The value of HorizontalResolutionProcessingLevelEnum is "Not provided". The LongitudeResolution translated to the XDimension element and the LatitudeResolution is translated to the YDimension element.

History

UMM Versioning

VersionDateWhat Changed
1.15.512/3/2020No changes were made for Spatial Extent during the transition from version 1.15.4 to 1.15.5
1.15.49/18/2020No changes were made for Spatial Extent during the transition from version 1.15.3 to 1.15.4
1.15.37/1/2020No changes were made for Spatial Extent during the transition from version 1.15.2 to 1.15.3
1.15.25/20/2020Added Statute Miles, Nautical Miles, and Not provided as valid values to the HorizontalDataResolutionUnitEnum element. Also Simplified VariesResolution and PointResolution by removing the non needed HorizontalResolutionProcessingLevelEnum sub element from version 1.15.1 to 1.15.2
1.15.13/25/2020No changes were made for Spatial Extent during the transition from version 1.15.0 to 1.15.1
1.15.02/26/2020
  • Changed the HorizontalDataResolutions element to HorizontalDataResolution and added sub element objects to aid in more clearer error messages when users make schema mistakes. Before the JSON schema validator spewed a lot of misleading error messages making it hard to figure out what the user did wrong.
  • Added a description for AdditionalAttributes/Name so that the help text shows up in MMT.
1.14.010/21/2019
  • Removed the HorizontalCoordinateSystem element from SpatialInformationType class
  • Added the ResolutionAndCoordinateSystem element with the ResolutionAndCoordinateSystemType definition to the HorizontalSpatialDomainType class.
  • Renamed HorizontalCoordinateSystemType class to ResolutionAndCoordinateSystemType.
  • Added the description element to the ResolutionAndCoordinateSystemType class
  • Removed the GeographicCoordinateSystem element and its class (GeographicCoordinateSystemType)
  • Added HorizontalDataResolutions element with the HorizontalDataResolutionType definition to the ResolutionAndCoordinateSystemType class and allowing multiple instances of this class.
  • The new HorizontalDataResolutionType class contains 7 choices with up to 8 new elements.
1.13.004/11/2019No changes were made for Spatial Extent during the transition from version 1.12.0 to 1.13.0
1.12.001/22/2019No changes were made for Spatial Extent during the transition from version 1.11.0 to 1.12.0.
1.11.011/28/2018No changes were made for Spatial Extent during the transition from version 1.10.0 to 1.11.0.
1.10.005/02/2018During the transition from version 1.9.0 to 1.10.0, the sub element 'VerticalSpatialDomainType' was enumerated.
