build_transform_and_save_weights
Generate and save spatial weights for GIS analysis by reading a shapefile, applying methods like queen, rook, or knn, transforming weights if needed, and exporting them in GAL or GWT format.
Instructions
Pipeline: Read shapefile, build spatial weights, optionally transform, and save to file.
Parameters:
- data_path: Path to point shapefile or GeoPackage
- method: 'queen', 'rook', 'distance_band', 'knn'
- id_field: Optional field name for IDs
- threshold: Distance threshold (required if method='distance_band')
- k: Number of neighbors (required if method='knn')
- binary: True for binary weights, False for inverse distance (DistanceBand only)
- transform_type: 'r', 'v', 'b', 'o', or 'd' (optional)
- output_path: File path to save weights
- format: 'gal' or 'gwt'
- overwrite: Allow overwriting if file exists
