Package Exports

leaflet-filelayer

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (leaflet-filelayer) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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({
        // 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);
    });
