How to include the script

The stylesheet is best included in the header of the document.

<link rel="stylesheet" href="css/photomap.css"/>

This include can be added to the header or placed inline before the script is invoked.

<script src="lib/requests.js"></script>
<script src="lib/togeojson.js"></script>
<script src="lib/leaflet-src.js"></script>
<script src="data/exif-data.js"></script>
<script src="data/gpx-data.js"></script>
<script src="js/photomap.js"></script>

Or use Require.js.

requirejs([
	"js/photomap.js",
	"lib/requests.js",
	"lib/leaflet-src.js",
	"lib/togeojson.js",
	"data/exif-data.js",
	"data/gpx-data.js"
], function(Photomap, requests, Leaflet, toGeoJSON, ExifData, GpxData) {
	...
});

Or use imported as a component in existing projects.

@import {Leaflet} from "lib/leaflet-src.js";
@import {requests} from "lib/requests.js";
@import {toGeoJSON} from "lib/togeojson.js";
@import {ExifData} from "data/exif-data.js";
@import {GpxData} from "data/gpx-data.js";
@import {Photomap} from "js/photomap.js";

How to build the script

This project uses leaflet.js from http://leafletjs.com/

This project uses node.js from http://nodejs.org/

The following commands are available for development:

• node node_scripts/importexif.js - Imports EXIF data and creates a JSON cache file.
• node node_scripts/importgpx.js - Imports GPS data and creates a JSON cache file.
