Agromonitoring - Historical NDVI API

Historical NDVI by polygon

Daily updating of NDVI for prompt monitoring of vegetation.

Description:

Detailed historical data for analysis and comparison vegetation of one season to another.

Archive since the 2001 year (only for the Corporate account).

NDVI is calculated based on a combination of imageries from Landsat, Sentinel and MODIS with daily updating.

NDVI (Normalized Difference Vegetation Index), EVI (Enhanced Vegetation Index) are the most common indicators for assessing vegetation progress over time.
