Abstract: A configurable automated system preprocesses weather and agronomic data to provide a yield forecast model for a target crop in an identified region. The system considers data typically excluded based on biases of a human operator and/or considers data otherwise not considered to be relevant and/or a powerful predictor by a person having ordinary skill in the art. The system builds predictive models through a variety of statistical approaches, selects and validates candidate models, and operates validated models that output in-season forecasts in a production environment.

Abstract: Described are systems, methods, and apparatus that gathers environment condition data from different sensors at various locations within an area, aggregates the environment condition data to produce aggregated environment condition scores for the area and provides the aggregated environment condition scores to different locations within the area. While sensor data from a single sensor/device, such as a camera may provide low quality environment information, by collecting and aggregating information from multiple sensors and/or locations in the area, highly accurate aggregated environment condition scores for environment conditions may be realized. The aggregated environment condition scores may be provided to various locations within the area as representative of the environment condition at that point in time within the area, regardless of whether those locations have sensors.
