Planted Area Computation🔗
📖 Overview🔗
The planted area computation analytic calculates the planted area of a crop field based on satellite imagery and emergence detection data. This process uses the emergence date as a reference and compares images taken before and after emergence to estimate the percentage of planted area. It supports different processing modes, including standard planted area calculation and control mode for unplanted area detection. The algorithm validates results using predefined thresholds and stores them for integration with other analytics and applications.
