Introduction | Synthetic Example Data | Core Covariate Pipeline | Methodological Details & Semantics | 1. Polygon Area (spat_area) | 2. Distance to Reference Features (spat_distance) | 3. Intersecting Feature Counts (spat_count) | 4. Linework Length inside Polygons (spat_length) | 5. Polygon Overlap Measures (spat_overlap) | 6. Raster Zonal Statistics (spat_raster) | Operation Diagnostics (spat_diagnostics) | Summary of Guarantees

The problem | Create IDs | Matching rules and ambiguity | Audit transitions | Visualize splits and mergers | Validate the result | Calibrate before production | Preserve IDs across reruns | Geometry and time controls | Interpretation limits
