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.

 

          ECO1BRAD files require a corresponding ECO1GEO file to determine coordinates for the scene. If the geolocation information is not available, the latitude and longitude will be listed as zero (0).

 

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

 

          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

 

          Latitude Format:

          DDMMSS.SSH

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

          H = Hemisphere with N for north and S for south

 

          ECO1BRAD files require a corresponding ECO1GEO file to determine coordinates for the scene. If the geolocation information is not available, the latitude and longitude will be listed as zero (0).

 

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.

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/ECOSTRESS/ECO1BRAD.001

 

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.

         DDD = Julian Day of Acquisition Start Date

         THHMMSS = Time of Acquisition in Hours, Minutes, Seconds

         Example:

         L1B_RAD_03732_002_20190303T202453

 

Local Granule ID

  • Field Definition:  The name of an individual file.

          Format:

          ECOSTRESS_PPPPPPP_OOOOO_SSS_YYYYDDDTHHMMSS_PGEV_VV.h5

          OOOOO = Orbit Number

          SSS = Scene Number (not included for ECO1BATT product)

          YYYY = Acquisition Year

          DDD = Julian Day of Acquisition Start Date

          THHMMSS = Time of Acquisition – Hours, Minutes, Seconds

          PGEV = Product Generation Algorithm Version

          VV = Version Number for data

          h5 = Data format

          Example:

               ECOSTRESS_L1B_ATT_03766_20190306T012256_0503_01.h5

 

Orbit Number

  • Field Definition:  The Orbit number is the sequential number of times the satellite traveled around the Earth when the data were collected.

 

 

Scene Number

  • Field Definition:  The Scene Number is a sub-set of the Orbit Number and identifies the swath acquisition associated with the data file.

 

Version Number

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