Coordinates - Degrees, Minutes, Seconds

• Field Definition:  The latitude and longitude of the scene 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

                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

                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
 

DOI Authority

• Field Definition:  The Digital Object Identifier (DOI) Authority provides the infrastructure for the registration and services for a persistent reference. The DOI authority is used along with the DOI Name to view the associated URL for the product.

              Example:
              http://dx.doi.org or 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.

                Example:
                10.5067/MEaSUREs/VCF/VCF5KYR.001
 

Entity ID

• Field Definition:  The EarthExplorer Entity ID naming convention is based on the Local Granule ID.

                 Format:
                 PPPPPPPP.YYYYDDD.VVV
                 PPPPPPPP= Product Short Name (Number of characters may vary by data set)
                 YYYY = Nominal Acquisition Year
                 DDD = Julian Start Day of Acquisition
                 VVV = Version Number

                 Example:
                 VCF5KYR_1985001_001
 

Local Granule ID

• Field Definition:  The name of an individual file provided by LP DAAC.

                 Format:
                 PPPPPPPP.YYYYDDD.VVV.YYYYDDDHHMMSS.tif
                 PPPPPPPP= Product Short Name (Number of characters may vary by data set)
                 YYYY = Nominal Acquisition Year
                 DDD = Julian Start Day of Acquisition
                 VVV = Version Number
                 YYYYDDDHHMMSS = Julian Date of Production
                 tif = Data Format

                Example:
                VCF5KYR_1991001_001_2018224205008.tif
 

Version Number

• Field Definition:  The data version for the VCF product.
