Methods to get utm zone number, epsg code or proj4 string from latitude and longitude.

installation

go get -u github.com/iwpnd/utmz

usage

func Zone(p Point)

Return the UTM zone number for a given point.

package main

import (
  "fmt"

  "github.com/iwpnd/utmz"
  )

func main() {
  z, err := utmz.Zone(52.25,13.37)

  if err != nil {
      fmt.Println(err)
      return
    }

  fmt.Printf(z)
}

Results in

33

func Epsg(p Point)

Return a UTM zones EPSG code at a given point.

package main

import (
  "fmt"

  "github.com/iwpnd/utmz"
  )

func main() {
  epsg, err := utmz.Epsg(52.25,13.37)

  if err != nil {
      fmt.Println(err)
      return
    }

  fmt.Printf(epsg)
}

Results in

32633

func Proj4(p Point)

Return an UTM zones proj4 string from a given point.

package main

import (
  "fmt"

  "github.com/iwpnd/utmz"
  )

func main() {
  proj4, err := utmz.Proj4(52.25,13.37)

  if err != nil {
      fmt.Println(err)
      return
    }

  fmt.Printf(proj4)
}
