func Cast ¶ added in v0.54.0

func Cast[M ~map[K]V, K comparable, V any](input M) map[K]any

Cast turns a map[K]V to a map[K]any, so values will downcast to 'any' type.

func EncodeBBox ¶ added in v1.5.0

func EncodeBBox(bbox geom.T) (*[]float64, error)

EncodeBBox encodes b as a GeoJson Bounding Box. adapted from https://github.com/twpayne/go-geom/blob/b22fd061f1531a51582333b5bd45710a455c4978/encoding/geojson/geojson.go#L525

func Inverse ¶ added in v0.54.0
