Quick Start
Here is a recipe for getting Landsat NDVI.
Access
ndvi.landsat denotes NDVI at 30m resolution generated from the Landsat constellation. Landsat has an 8-day revisit cycle. Access it by setting variable to a list that includes ndvi.landsat. For example:
ndvi_request = {
'variable': ['ndvi.landsat'],
'space': [[-90.72529, 40.67410]], # Single US corn farm
'time': {
'start':'2019',
'end':'2022',
}
}

Sample Output
| time | point | lat | lon | ndvi.landsat | qa.landsat |
|---|---|---|---|---|---|
| 2019-01-01 | 0 | -90.72529 | 40.67410 | 0.242341 | 1.0 |
| 2019-01-02 | 0 | -90.72529 | 40.67410 | 0.276321 | 0.0 |
Field Definitions
| Column | Description |
|---|---|
| time | The date of the NDVI measurement. (UTC) |
| point | an integer identifier unique to each location in the request |
| lat, lon | the latitude and longitude |
| ndvi.landsat | NDVI |
| qa.landsat | a floating point number where 1.0 indicates the NDVI value is valid; 0.0 indicates it is invalid (because no good image was available that day.) |
