Maps

One of the formats we can work is KML. Use Google Earth to create maps with dots, routes, areas and photos. Export this maps in KML files that can be added to the site.

You can also export a KML file from Google Maps and use it. Google Maps is very popular, so we can use this feature to import maps made by others.

Please note this is just a quick example, not a real map. The KML format allows us to create excellent maps.

Leaflet is a widely used open source JavaScript library created to build web mapping applications.

And as Open Street Map does not require an API key, we are starting to use Leaflet and Open Street Maps to build complex responsive maps that can run in practically any web page.
