Open Canal Map comes in three flavors: Google Maps overlay, Android app and iPhone/iPad app. The Andoid and iPhone apps are built using Mapbox. This means they can offer a more intuitive interface while boating. The Google Maps version allows you to search for shops and travel directions from withing the Google Maps App – available for Android and iPhone.
All versions feature the same dataset which is constantly growing. If you notice a nice mooring, laundrette or something else you think should be on there – just go ahead and add it to the map. The contributions people submit make this map.
