I have a problem today with the Nominatim reverse geocoder for Leaflet.

I found a solution on github : https://github.com/perliedman/leaflet-control-geocoder , but I don't know how to use it.

I can use the mapzen solution for the normal geocoding but for the reverse it doesn't work...

In fact, I have a HTML page which contains a leaflet map at the right, and a toggle menu at the left. In this menu, I have a mathematic tool which make some treatments to find some Lat Long coordinates. Those coordinates appears in a with the dd.dddddddd format.

And I want this LatLong result to be located on my map with a point and a toggle popup.

I've made a little Schema to illustrate my needs :


I've tried to put a "L.popup" solution but it doesn't work :


function onMapClick(e) {
        .setContent("The coordinates are" + ['sch-lvpk-lat','sch-lvpk-long'].toString())

map.on('click', onMapClick);

The 'sch-lat','sch-long' are the html inputs in which we have lat long values.

And I also tried to make a Nominatim reverse geocoding by using leaflet-control-geocoder but I don't know how to use it... I made this :

L.control.showAll({bounds: L.latLngBounds(L.latLng(41.058, 9.257), L.latLng(51.009, -5.295))}).addTo(map);
L.control.scale({options: {position: 'bottomleft',maxWidth: 100,metric: true,imperial: false,updateWhenIdle: false}}).addTo(map);

But it doesn't work neither...

If you have another solution I accept it :D

  • You have tool that generates a Lat/Long and you want to locate that point. You don't need a geocoder to zoom to a point and create a popup. A reverse geocoder would accept Lat/Longs and return a Street Address. Which problem do you really need help on? Jan 30, 2017 at 15:21
  • My problem is that I have a leaflet map on a side and a menu with mathematic treatments on an other side. In the menu, I have 2 HTML inputs which contain Lat/Long values resulting by the mathematic treatment. I want to use those Lat/Long values to make a popup on my map. It seems to be easy, but my problem is the fact that those Lat/Long values are generated by treatments which would be made by other people (Kilometer Point conversion to Lat/Long). So, those HTML inputs are generated automatically and it change at every PK to Lat/Long conversion.

This may work:

<!DOCTYPE html>
    <link rel="stylesheet" href="https://unpkg.com/leaflet@1.0.3/dist/leaflet.css" />
    <script src="https://unpkg.com/leaflet@1.0.3/dist/leaflet.js"></script>

#header    { width: 100%;height: 25px; float: left; font:14px Verdana;font-weight:bold}
<div id="header"> 
          Lat:  <input type="text" id="lat">
          Long:  <input type="text" id="lng">
          <button onclick="buttonClick()">Click</button>
<div id="map" style="width: 600px; height: 400px;"></div>


var map = L.map('map').setView([42.736424, -73.762713], 8);  

var osm=new L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png',{ 
            attribution: '&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'});

// used to populate the two textboxes
var theSampleLat = 42.682435;
var theSampleLng = -73.78967;

document.getElementById("lat").value = theSampleLat;
document.getElementById("lng").value = theSampleLng;

function buttonClick(){
    //Get values from textboxs
    var theLat = document.getElementById("lat").value;
    var theLng = document.getElementById("lng").value;

    //Make marker
    .bindPopup("Your point is at " + theLat+", "+theLng).openPopup();

    map.setView([theLat,theLng], 15);


  • yes this works and how I would do this to.

  • Your app had Lat/Long textboxes, like mine. put a button that when clicked reads the values, and creates the marker/popup and zooms to it. My buttonClick function does basically that. You should eb able to copy/modify it to work in your app. Jan 31, 2017 at 16:13
