Some resources for Paddlers are machine- readable through an API.

API stands for Application Programming Interface. "We have an API" is tech-speak for saying "there's a way for your program/resource/website to get data from us or send it to us.

So this is something only Developers care about. But it is at the core of the idea that different projects can work together and profit from it. It is the technical basis of automated data exchange.
For example, Rivermap/riverzone provides data like waterlevels etc. to RiverApp, Riverlog and whitewater.guide. It does so through an API.

Projects that provide an API


RiverZone started as a replacement for the ailing and unmaintained water level page on CKFiumi website and later merged with the Rivermap project.

The Riverzone webpage remains as a resource for the Italian kayaking community and as a way for me to experiment with new data (like, for example, per-river-section Point of Interests) and new UI approaches.


The mobile app aims to provide all the information a paddler might need for a kayaking trip or a quick run. The app features detailed guidebooks, water levels, filters, maps, pictures, videos, ratings, tags. Users can submit content.

It's an international solution with English being the primary language and Spanish, French German, Russian being the secondary languages.

Content of the app

We have different quality of content for different regions.


Rivermap visualizes the navigability of river sections on an interactive map to give canoeists the best possible and quick overview of the current situation. The individual sections are color-coded depending on the water level and information recorded by paddlers provides valuable additional information. Using filters and linked data, the current situation and further developments can be analyzed more precisely.
