title: AGIcam Dataset: In-Field IoT Sensor Data for Wheat Phenotyping and Yield Prediction

description: Description:

AGIcam is an affordable, solar-powered Raspberry Pi-based IoT sensor system designed for high-frequency, plot-level data acquisition. Data from the AGIcam system were used to develop time-series models of wheat yield using machine learning (Random Forest) and deep learning (Long Short-Term Memory, LSTM). This dataset provides the raw and preprocessed inputs used in those analyses.

The dataset accompanies the manuscript “AGIcam: An Open-Source IoT-Based Camera System for Automated In-Field Phenotyping and Yield Prediction.” The dataset includes synchronized vegetation index (VI) metrics, weather data, and related agronomic trait data, along with sample images collected with the AGIcam system during spring and winter wheat field trials in the 2022 growing season. 

Dataset Content:



Vegetation Index, Weather, and Agronomic Trait Data (Spring_wheat_data.csv and Winter_wheat_data.csv)The AGIcam dataset includes synchronized vegetation indices, weather measurements, and agronomic trait data. Each row in the dataset represents a single VI measurement extracted from AGIcam images, paired with weather parameters recorded at the corresponding time point. Plot-level heading date and grain yield (kg/ha) are included for downstream phenotyping and modeling applications.
