Whitewater sports for canoeists, rafters and others.

OpenSeaMap includes information for whitewater sports, including for canoeist, rafters and others. See WikiProject Whitewater Maps to join the people behind this work.


A river is a watercourse that is too wide to jump over it. Rivers are wide enough to be traveled by kayak or canoe. Take a waterproof GPS with (or packed waterproof), tie it firmly, and measure the exact course of the river. Note important points (set a track point, describe it by voice recorder, photo), and draw the map.

All rivers with width more than 5 meters has to be draw by waterway=riverbank or natural=water+water=river in addition to waterway=river.

If there is a tributary: please connect the two waterways together (not only the riverbanks).

These are subjective in the good sense of the term. See the International Scale.

If you don't know a grade or can't decide set it to "unknown". If you don't know about river practise, don't map it at all.

What How Key and Value Icon Remarks
isolated rapid Node whitewater:rapid_grade=# Grade 1 | 2 | 3 | 4 | 5 | 6
name of rapid Node whitewater:rapid_name=*
sections Way whitewater:section_grade=# section of waterway=river (split in JOSM by <Strg-p>)
Grade 1 | 2 | 3 | 4 | 5 | 6 (see International Scale)

Each section starts at a whitewater=put_in or whitewater=put_in;egress,
and ends at a whitewater=egress or whitewater=put_in;egress.
the grade of a section is similar to the most difficult rapid in the section (if no portage possible).

name of section Way whitewater:section_name=*

(White water classification follows its own subjectives rules not only described by these pictures, see International Scale)

+ a lot of additional informations

A selection of additional values have been used in some areas with the whitewater key (see here for an analysis of values used). One used more than 100 times but not listed above is whitewater=portage_way. The key 'canoe' has been used by a few people (analysis) as has the key 'kayak' (analysis). Several suggestions have been made on the talk page for WikiProject_Whitewater_Maps for ways to ensure that this tagging scheme is compatible with tags of use for non-whitewater paddling, including the use of paddlecraft=put_in;egress (for flat-water or sea locations).

There are some existing/developing useful tagging conventions around access information - see details of: access=* or boat=* or canoe=* at Access, and boat=* at Key:boat and also a proposal at Proposed features/access restrictions 1.5.

There are also some existing/developing conventions about water coverage which may be useful (where, for example, an island may only appear occasionally). See Proposed_features/Water_cover. Current formal suggestions are for water=intermittent and water=tidal.

Whitewater Map

Whitewater Map

OpenSeaMap shows a Whitewater-chart. Use the "Sport"-layer in menu "View > Sport" with all rivers worldwide. Kayaks and canoeing tours are displayed by colours, according to their difficulty (starting in zoom level = 9). Put in and egress are marked, also hazards and portages. OpenSeaMap is the follower of the British WhiteWater Map. [1] [2]
