Advanced Very High Resolution Radiometer Phenology Data Dictionary
The Data Dictionaries are a set of information describing the contents, format, and structure of elements for EarthExplorer products.
- Field Definition: The first day of data acquisition for the source data at the end of the collection period. The begin date and end date are used to indicate the date range for the annual metrics.
Format:
YYYY/MM/DD
YYYY = Year
MM = Month
DD = Day
- 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:
