Loads local files (GeoJSON, GPX, KML) into the map using the HTML5 FileReader API

Leaflet.FileLayer

Loads local files (GeoJSON, GPX, KML) into the map using the HTML5 FileReader API, without server call !

  • A simple map control
  • The user can browse a file locally
  • It is read locally (FileReader) and converted to GeoJSON
  • And loaded as a layer eventually!

Check out the demo !

For GPX and KML files, it currently depends on Tom MacWright's togeojson.js.

    var map = L.map('map').fitWorld();
    ...
    L.Control.fileLayerLoad({
        // See http://leafletjs.com/reference.html#geojson-options 
        layerOptions: {style: {color:'red'}},
        // Add to map after loading (default: true) ? 
        addToMap: true,
        // File size limit in kb (default: 1024) ? 
        fileSizeLimit: 1024,
        // Restrict accepted file formats (default: .geojson, .kml, and .gpx) ? 
        formats: [
            '.geojson',
            '.kml'
        ]
    }).addTo(map);

Events:

    var control = L.Control.fileLayerLoad();
    control.loader.on('data:loaded', function (e) {
        // Add to map layer switcher 
        layerswitcher.addOverlay(e.layer, e.filename);
    });
