Quick Start
Here is a recipe for getting a daily, 10m resolution NDVI time series from Streambatch (ndvi.streambatch)
Access
ndvi.streambatch denotes Streambatch NDVI which is daily, 10m resolution NDVI for every point on Earth with history to 2013. It is constructed through the fusion of satellite imagery from the Sentinel-2, Landsat, and MODIS constellations. This is the highest resolution, highest frequency NDVI data available from Streambatch.
Access it by setting variable to a list that includes ndvi.streambatch For example:
ndvi_request = {
'variable': ['ndvi.streambatch'],
'space': [[-90.72529, 40.67410]], # Single US corn farm
'time': {
'start':'2019',
'end':'2022',
'unit':'day',
}
}

Sample Output
| time | point | lat | lon | ndvi.streambatch | source.streambatch |
|---|---|---|---|---|---|
| 2018-01-01 | 0 | -20.7829 | -44.14913 | 0.452341 | 1.0 |
| 2018-01-02 | 0 | -20.7829 | -44.14913 | 0.460321 | 1.0 |
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.streambatch | NDVI |
| source.streambatch | a floating point number denoting the satellite system from which NDVI was derived. See table below for mappings. |
source.streambatch mappings
| Source Code | Constellation |
|---|---|
| 3.0 | Sentinel-2 |
| 2.0 | Landsat |
| 1.0 | MODIS |
| 0.0 | No new data was available; NDVI is an extrapolation. |
Caveats
The maximum polygon size for ndvi.streambatch is 1000 hectares.
