Spatial helpers: bbox, haversine, nearest station, mask filtering.

Functions

bbox_contains(outer, inner)	True if outer bbox fully contains inner.
bbox_hash(bbox)	Short deterministic hash of a bounding box for filenames.
expand_bbox(bbox, radius_km)	Expand bbox by radius_km in all directions (approximate, WGS84).
filter_locations_by_bbox(locations, bbox)	Keep locations inside bbox.
filter_locations_by_geometry(locations, ...)	Keep locations that fall inside a shapely geometry (spatial join).
geometry_to_bbox(geometry)	Extract (xmin, ymin, xmax, ymax) from a shapely geometry.
haversine_km(lon1, lat1, lon2, lat2)	Great-circle distance in km (WGS84).
load_mask_geometry(path)	Load a spatial mask from vector (SHP/GPKG/GeoJSON) or raster (TIF).
load_mask_geometry_wgs84(path)	Load a spatial mask and reproject to WGS84 (EPSG:4326).
nearest_location(x, y, locations, *[, ...])	Return closest location to (x, y).
