projected (to meter):

	def calc_distance(geojson: str):
		from shapely.geometry import LineString
		from shapely.ops import transform
		from functools import partial
		import pyproj
		track = LineString(json.loads(geojson)['coordinates'])
		project = partial(
			pyproj.transform,
			pyproj.Proj(init='EPSG:4326'),
			pyproj.Proj(init='EPSG:32633'))
		return transform(project, track).length
