Global Land Survey 2000 ETM Plus Data Dictionary
The Data Dictionaries are a set of information describing the contents, format, and structure of elements for EarthExplorer products.
- Field Definition: The date the image was acquired.
Format:
YYYY/MM/DD
- Field Definition: This flag identifies whether or not the entity has a browse image available with it. A browse image provides the user with a visual overview of an inventory item. The browse image is an online digitally subsampled raster image.
Valid Codes:
Y = Yes
N = No
- 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
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 datum associated with the image.
Valid Code:
WGS 84 = Worldgeodetic System 1984
- Field Definition: This field uniquely identifies the individual landsat scene.
Example:
P029R030_7X20001005
Valid Format: PpppRrrrsXyyyymmdd
P = WRS Path Number; next three characters
ppp = WRS Path number
R = WRS Row Number; next three characters
rrr = WRS Row number
s = Satellite number
X = reserved space for future use
yyyy = Year of acquisition
mm = Month of acquisition
dd = Day of acquisition
- Field Definition: The orientation of the image.
Values:
Valid code = NUP (North Up)
- Field Definition: Estimated percentage of scene missing or unusable
Values:
Valid Values = 0 - 100
- Field Definition: The resampling applied to the scene.
Valid Codes:
CC = Cubic Convolution
NN = Nearest Neighbor
- Field Definition: The size of all files associated with the scene.
- Field Definition: The sensor that acquired this data.
- Field Definition: The satellite which acquired the data.
- Field Definition: The Sun azimuth angle at the "true" WRS scene center. Azimuth is the angle of horizonal deviation, measured clockwise from the north.
Values:
-180.0000000 through +180.0000000 degrees (with 7-digit precision)
NOTE: A positive value
- Field Definition: The Sun elevation angle at the "true" WRS scene center. Elevation is the angle of vertical deviation from the tangent to the earth's surface (at scene center point) to the line between the sun's center and the scene center point. NOTE: The solar zenith angle will be 90 degrees minus the solar elevation angle.
Values:
0 through +90.0000000 (with a 7-digit precision)
- Field Definition: The WRS-2 Path number associated with the scene.
Values:
001 through 233
- Field Definition: The WRS-2 Row number associated with the scene.
Values:
001 through 244
- Field Definition: The UTM zone number associated with the image.
