Historical Potential Score¶

📖 Overview¶

The Historical Potential Score analytic provides an indicator of the average potential score over past years for a selected crop and season, based on cumulative NDVI (Normalized Difference Vegetation Index). It serves as a benchmark to compare field performance across different areas within a region or across different years. A Risk Score is also provided based on the variability of the past seasons.

The figure below illustrates the expected NDVI development for a typical annual grain crop. The analytic transforms the NDVI time series into a potential score, enabling comparisons between fields in the same region or across historical seasons.

📜 Rules for Defining Historical Periods¶

If historicalSeasons is provided:¶

• If 3 or more years are provided:
• Use them directly to compute potential and risk scores.
• If fewer than 3 years:
• If year is provided:
  • start_year = year - 5
  • end_year = year - 1
• If year is not provided:
  • end_year = max(historicalSeasons)
  • start_year = end_year - 4

If only year is provided:¶

• start_year = year - 5
• end_year = year - 1

If neither is provided:¶

• A ValueError is raised.
