Types

type Geo2TzRTreeIndex

type Geo2TzRTreeIndex struct {
	// contains filtered or unexported fields
}

func NewGeo2TzRTreeIndexFromGeoJSON

func NewGeo2TzRTreeIndexFromGeoJSON(geoJSONPath string) (*Geo2TzRTreeIndex, error)

NewGeo2TzRTreeIndexFromGeoJSON creates a new Geo2TzRTreeIndex from a GeoJSON file

func (*Geo2TzRTreeIndex) Insert

func (g *Geo2TzRTreeIndex) Insert(min, max [2]float64, element timezoneGeo)

Insert adds a new timezone bounding box to the index

func (*Geo2TzRTreeIndex) Lookup

func (g *Geo2TzRTreeIndex) Lookup(lat, lng float64) (tzID string, err error)

Lookup returns the timezone ID for a given latitude and longitude if the timezone is not found, it returns an error It first searches in the land index, if not found, it searches in the sea index
