Hi,

I would like to extract all navigable rivers from the OSM data. http://en.wikipedia.org/wiki/Navigability

I know the tools and processes, but I cannot figure out the combination of tags I should use to filter the data. If I take all ways with tags river,riberbank,canal, then I get huge amounts of data and most of the rivers are small/narrow and not navigable.

Could anyone suggest additional tags to filter the rivers by?

It looks like you're going to have to make some assumptions about what kind of waterway is navigable and what isn't. Only a few waterways have been tagged as navigable=*, possibly because it's hard to ensure the verifiability of such a tag.

Many waterways have been tagged with legal permissions using the boat=* tag, but obviously this says nothing about the suitability of such waterways for navigation.
