Constants

const EarthRadius = 6378.137

EarthRadius is a rough estimate of earth's radius in km at latitude 0 if earth was a perfect sphere.

Variables

var GeoJSON = make(map[string][]byte)

GeoJSON is a cache of the NYC Subway Station and Line data.

var Stations = rtree.NewTree(2, 25, 50)

Stations is an RTree housing the stations

Types

type Station

type Station struct {
	// contains filtered or unexported fields
}

Station is a wrapper for `*geojson.Feature` so that we can implement `rtree.Spatial` interface type.

func (*Station) Bounds

func (s *Station) Bounds() *rtree.Rect

Bounds implements `rtree.Spatial` so we can load stations into an `rtree.Rtree`.

func (*Station) Point

func (s *Station) Point() cluster.Point

Point enables clustering over `Station`s.
