ndvi.modis

📘

Quick Start

Here is a recipe for getting MODIS NDVI.

Access

ndvi.modis denotes NDVI at 250m resolution generated from the MODIS constellation. MODIS has a daily revisit cycle. Access it by setting variable to a list that includes ndvi.modis. For example:

Python

ndvi_request = {
    'variable': ['ndvi.modis'],
    'space': [[-90.72529, 40.67410]], # Single US corn farm
    'time': {
        'start':'2019',
        'end':'2022',
    }
}

Output

Sample Output

time	point	lat	lon	ndvi.sentinel2	qa.sentinel2
2019-01-01	0	-90.72529	40.67410	0.622241	1.0
2019-01-02	0	-90.72529	40.67410	0.654261	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.modis	NDVI
qa.modis	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.)
