Active
By Earth Resources Observation and Science (EROS) Center June 17, 2021

The Data Dictionaries are a set of information describing the contents, format, and structure of elements for EarthExplorer products.

 

 

Acquisition End Date

  • Field Definition:  The last day of data acquisition.

          Format:

              YYYY/MM/DD

 

Acquisition Start Date

  • Field Definition:  The first day of data acquisition.

          Format:

               YYYY/MM/DD

 

Coordinates - Decimal Degrees

  • Field Definition:  The latitude and longitude are provided in decimal degrees for the following fields:

          Values:

          Scene Center Latitude and Longitude

          Northeast (NE) Corner Latitude and Longitude

          Northwest (NW) Corner Latitude and Longitude

          Southeast (SE) Corner Latitude and Longitude

          Southwest (SW) Corner Latitude and Longitude

 

          Latitude Format Decimal Degrees: -90.000 through 90.000

          Longitude Format Decimal Degrees: -180.000 through 180.000

 

          Number of decimal places will vary by dataset – check collection in EE.

 

Coordinates - Degrees, Minutes, Seconds

  • Field Definition:  The latitude and longitude are provided in degrees, minutes, and seconds for the following fields:

          Values:

          Scene Center Latitude and Longitude

          Northeast (NE) Corner Latitude and Longitude

          Northwest (NW) Corner Latitude and Longitude

          Southeast (SE) Corner Latitude and Longitude

          Southwest (SW) Corner Latitude and Longitude

 

          Latitude Format:

          DDMMSS.SSH

          DD = Degree(s) with a range of 0 through 90

          MM = Minutes(s) with a range of 0 through 59

          SS.SS = Second(s) with a range of 0 through 59.99

          H = Hemisphere with N for north and S for south

 

         Longitude Format:

         DDDMMSS.SSH

         DDD = Degree(s) with a range of 0 through 180

         MM = Minute(s) with a range of 0 through 59

         SS.SS = Second(s) with a range of 0 through 59.99

         H = Hemisphere with E for east and W for west

 

DOI Authority

  • Field Definition:  System that provides an infrastructure for the registration and persistent reference of a Digital Object Identifier. The DOI name can be entered into a DOI Authority system to view the associated URL for the product.

         Example:

         https://doi.org

 

DOI Name

  • Field Definition:  Digital Object Identifier is used to uniquely and permanently identify a dataset. The DOI name is more stable than a URL and is used as a permanent reference for the product. The DOI name can be entered into a DOI Authority system to view the associated URL for the product.

         Values:

         (prefix)/(suffix)

         Prefix – 10.(number) where (number) identifies registrant agent. 5067 has been assigned for NASA ESDIS.

         Suffix – uniquely identifies the data item and its format is assigned and managed by the registrant agent.

         Example:

         10.5067/MEaSUREs/LSTE/CAM5K30CF.002

 

Entity ID

  • Field Definition:  The naming convention of each file is based on the Local Granule ID. The Entity ID may match the Local Granule ID for some data sets.

           Format:

           PPPPPPPP_xxxx_YYYYMM_VVVV.nc

 

           PPPPPPPP = Product Short Name (Number of characters may vary by data set)

           xxxx = Product Type (coef = coefficient, emis = emissivity, emis_uncertainty = emissivity uncertainty)

           YYYY = Acquisition Year

           MM = Acquisition Month

           VVVV = Version Number

           nc = Data Format

           Example:

           CAM5K30CF_coef_200407_V002.nc

 

Local Granule ID

  • Field Definition:  The name of an individual file.

          Format:

          PPPPPPPP_xxxx_YYYYMM_VVVV.nc

 

          PPPPPPPP = Product Short Name (Number of characters may vary by data set)

          xxxx = Product Type (coef = coefficient, emis = emissivity, emis_uncertainty = emissivity uncertainty)

          YYYY = Acquisition Year

          MM = Acquisition Month

          VVVV = Version Number

          nc = Data Format

          Example:

          CAM5K30CF_coef_200407_V002.nc
