coordinate

English | 中文

A golang library for geographic coordinate conversions, supporting the following coordinate systems:

• WGS84
• Web Mercator
• Mercator
• GCJ02

Feature

• Convert coordinates between this coordinate systems

Install

$ go get -u github.com/Icemap/coordinate

Example

GCJ02 coordinate system to WGS84 coordinate system

import "github.com/Icemap/coordinate"

gcj02Point := Coordinate{X: 110.0, Y: 20.0}
wgs84Point, err := coordinate.Convert(coordinate.GCJ02, coordinate.WGS84, gcj02Point)

GCJ02 coordinate system to Web Mercator coordinate system

import "github.com/Icemap/coordinate"

gcj02Point := Coordinate{X: 110.0, Y: 20.0}
webMercatorPoint, err := coordinate.Convert(coordinate.GCJ02, coordinate.WebMercator, gcj02Point)
