Harvest Date - Beta
The Ag-Analytics Harvest Date API provides the service which can trace back within a given year when a crop was harvested on the field.
Harvest Date
In the modern agriculture industry, people often use a crop calendar, Growing Degree Days (GDD), or self-reports to predict or trace back the crop harvest date for a given year. However, the information coming from the historical crop calendar or the estimated GDDs can be inaccurate for local regions and misleading, especially in a year with cooler or warmer spring.
The Ag-Analytics Harvest Date API provides the service which can trace back within a given year when a crop was harvested on the field. This service is developed from our near real-time ground truth agriculture data, historical weather and soil data, and weekly high-resolution remote sensing imagery. It provides a near-real-time harvest date prediction within a given year with the spatial resolution at 8m. Users can provide a polygon of their field in specific formats and the year of interest to retrieve the estimated harvest date.
