A simple Go package to convert coordinates in Lambert projections system to GPS WGS84 coordinates. It is based on the [IGN algorithms and methods](http://geodesie.ign.fr/contenu/fichiers/documentation/algorithmes/notice/NTG_71.pdf)

# Install

```

go get gopkg.in/yageek/lambertgo.v1

```

# Usage

```go

import lgo "github.com/yageek/lambertgo"

import "fmt"

//Declares origin point

var point *lgo.Point= &lgo.Point{994272.661,113467.422,0,lgo.Meter}

//Converts pointOrg in Lambert Zone 1 to WGS84 - Results in Radian

point.ToWGS84(lgo.LambertI)

//Converts to Degree

point.ToDegree()

fmt.Printf("Latitude:%.5f - Longitude:%.5f",point.Y,point.X)

```

```go

import lgo "github.com/yageek/lambertgo"

import "fmt"

//Declares origin point

var point *lgo.Point= &lgo.Point{2.228389, 48.824054,0,lgo.Degree}

//Converts to Radian

point.ToRadian()

//Converts pointOrg in WGS84 to Lambert Zone 1  - Results in Meter

point.ToLambert(lgo.LambertI)

fmt.Printf("X:%.5f - Y:%.5f",point.X,point.Y)

```
