leaflet-filelayer

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.

Usage

    var map = L.map('map').fitWorld();
    ...
    L.Control.fileLayerLoad({
        // Allows you to use a customized version of L.geoJson.
        // For example if you are using the Proj4Leaflet leaflet plugin,
        // you can pass L.Proj.geoJson and load the files into the
        // L.Proj.GeoJson instead of the L.geoJson.
        layer: L.geoJson,
        // 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);
