A Leaflet control to display the coordinates of the map center, especially useful on touch/mobile devices

View project on GitHub

Usually in mobile or touch devices there is no pointer. The alternative is, for example, display the coordinates of the map center.


  • Download latest release

    • Source code in /src folder
    • Minified versions in /dist
  • Include js and css files located in the /dist folder (production) or /src (development)

<!-- Production--> 
<link rel="stylesheet" href="dist/L.Control.MapCenterCoord.min.css" />
<script src="dist/L.Control.MapCenterCoord.min.js"></script>
<!-- Development / debug --> 
<link rel="stylesheet" href="src/L.Control.MapCenterCoord.css" />
<script src="src/L.Control.MapCenterCoord.js"></script>
  • Then create a MapCenterCoord control and add it to map:

Projected coordinate system and change crosshair icon

Show projected coordinates and change crosshair icon.

  • Link proj4.js library and Proj4Leaflet in your HTML document, define projection and configure map:
<script src="">
<script src="./lib/proj4leaflet.min.js"></script>
var etrs89N31 = new L.Proj.CRS(
  "EPSG:25831", "+proj=utm +zone=31 +ellps=GRS80 +units=m +no_defs", {
  origin: [238379.2278, 4265559.3497],
  resolutions: [
    305.75, 152.87, 76.437, 38.219, 19.109, 9.5546, 4.7773, 2.3887, 1.1943, 0.5972


var map ='map', {
  crs: etrs89N31,
  center: [39.588, 2.935],
  zoom: 0,
  layers: [orto],
  continuousWorld: true
  • Define new crosshair icon using css:
.leaflet-control-mapcentercoord-icon {
  background: url(../dist/icons/MapCenterCoordIcon2.svg) 50% 50% no-repeat;
  • Configure MapCenterCoord control (update map center coordinates while dragging, no decimals and edit template):
  iconFile: 'MapCenterCoordIcon2.png',
  template: '<b>ETRS89 UTM31N</b><br>x:{x} y:{y}',
  projected: true,
  onMove: true,
  formatProjected: '#.##0,'
