GeoAI Tutorials - Agricultural Field Boundary Delineation (Instance Segmentation) with GeoAI

Learn an end-to-end GeoAI workflow for agricultural field boundary delineation using instance segmentation and the Fields of the World dataset (https://fieldsofthe.world). In this tutorial, you’ll learn how to: • Explore and visualize field boundary data (PMTiles web map) • Understand why instance segmentation works better than semantic segmentation for adjacent fields • Prepare training data and image chips • Train an instance segmentation model • Run inference and post-processing • Export vector boundaries with customizable thresholds • Scale to batch processing for large areas This workflow can be adapted to detect other object types (not just field boundaries) as long as training data is available.
