Calibration Validation (Cal/Val) Reference Sites Data Dictionary
The Data Dictionaries are a set of information describing the contents, format, and structure of elements for EarthExplorer products.
- Field Definition: The dataset associated with the scene.
Valid Codes:
EO1-ALI
EO1-HYPERION
ETM+ (Landsat ETM+)
MSS (Landsat MSS)
SRTM
TM (Landsat TM)
- Field Definition: The naming convention of each scene is based on acquisition parameters.
Values:
EO-1 ALI and Hyperion
Format: EO1SPPPRRRYYYYDDDXXXML_GGG_VV
Where:
EO1 = Satellite
S = Sensor (H=Hyperion A=ALI)
PPP = Target WRS Path
RRR = Target WRS Row
YYYY = Year of Acquisition
DDD = Julian Day of Acquisition
X (0=off; 1=on) Hyperion
X (0=off; 1=on) ALI
X (0=off; 1=on) AC
M = Pointing Mode*
L = Scene Length**
GGG = Ground/Receiving Station
VV = Version Number
*Pointing Mode
N = Nadir
P = Pointed within Path/Row
K = Pointed outside Path/Row
**Scene Length
F = Full Scene
P = Partial Scene
Q = Second Partial Scene
S = Swath
0 - 9 = Special Modes 0 - 9
Remainder of alphabet are EDC collects
Example Landsat Entity ID: LE70010052009186EDC00
Format: LXSPPPRRRYYYYDDDGSIVV
Where:
L = Landsat
X = Sensor (M = MSS, T = TM, E = ETM+)
S = Satellite
PPP = WRS Path
RRR = WRS Row
YYYY = Year of Acquisition
DDD = Julian Day of Acquisition Year
GSI = Ground Station Identifier
VV = Version
Example SRTM Entity ID: SRTM1N29W083
Format: DDDDRHLLHLLLVV
Where:
DDDD = Dataset designator (SRTM)
R = Resolution (1 = 1 Arc-Second US Coverage, 3 = 3 Arc-Second Global Coverage)
H = Hemisphere (N = North, S = South Hemisphere)
LL = Lower Left Corner Latitude
H = Hemisphere (E = East, W = West Hemisphere)
LLL = Lower Left Corner Longitude
VV = Version (1 = SRTM Non-Void Filled, 3 = 1 Arc-Second Global)
