Functions

func Distance

func Distance(latA, lngA, latB, lngB float64) float64

Distance calculate the distance between point(latA, lngA) and point(latB, lngB), unit in meter.

func GCJtoWGS

func GCJtoWGS(gcjLat, gcjLng float64) (wgsLat, wgsLng float64)

GCJtoWGS convert GCJ-02 coordinate(gcjLat, gcjLng) to WGS-84 coordinate(wgsLat, wgsLng). The output WGS-84 coordinate's accuracy is 1m to 2m. If you want more exactly result, use GCJtoWGSExact/gcj2wgs_exact.

func GCJtoWGSExact

func GCJtoWGSExact(gcjLat, gcjLng float64) (wgsLat, wgsLng float64)

GCJtoWGSExact convert GCJ-02 coordinate(gcjLat, gcjLng) to WGS-84 coordinate(wgsLat, wgsLng). The output WGS-84 coordinate's accuracy is less than 0.5m, but much slower than GCJtoWGS/gcj2wgs.

func WGStoGCJ

func WGStoGCJ(wgsLat, wgsLng float64) (gcjLat, gcjLng float64)

WGStoGCJ convert WGS-84 coordinate(wgsLat, wgsLng) to GCJ-02 coordinate(gcjLat, gcjLng).
