- Field Definition: The first day of data acquisition
Format:
YYYY/MM/DD
- 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

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
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
- Field Definition: The date the data file was entered into the database.
Format:
YYYY/MM/DD
- Field Definition: The date the data file was last updated in the database.
Format:
YYYY/MM/DD
- Field Definition: This field uniquely identifies the granule id of the individual scene.
Format:
LatLon.PPPPPPP
Lat = Latitude for the lower left corner of the 1 x 1 degree tile (N = North, S = South hemisphere)
Lon = Longitude for the lower left corner of the 1 x 1 degree tile (E = East, W = West hemisphere)
PPPPPPP = Product Short Name (Number of characters may vary by data set)
Example:
N34E032.SRTMGL1
- Field Definition: The resolution identified the pixel size in arc-seconds.
Values:
1 arc-second (approximately 30 meters)
3 arc-second (approximately 90 meters)
30 arc-second (approximately 1,000 meters)
- Field Definition: The version number of the data set.
