Where does the information in the app come from?

Our app always contains the latest information on waterways, marinas, bridges, locks and more. Waterkaarten is the only app to offer this information conveniently in 1 app.

In addition, we use public sources like Rijkswaterstaat. We also work with organisations such as Varen Doe Je Samen! and harbour masters.

The maps themselves are based on the water maps of the ANWB (2018). Since then we’ve been keeping them up to date and developing them.

Another very important source for up-to-date information are our users, including you! A lot of people who use our app send us corrections and provide feedback. Our editorial team reviews these messages and includes them in the maps.

More than 60.000 people use our app each year. Having such a large number of users helps keep our app more accurate and up to date than others on the market.
