I mapped the water area around Venice and between Venice and Bibione. I mapped all rivers, canals and other water areas. I assigned
natural=water / waterwy=canal / boat=yes or no / coastline and so on to separate areas where boats can travel and other areas, where it is better not to enter by boat.
What are the possibilities to get an output of open streetmap with well symbolized areas fit for boat traffic and not. If you have an look to the lagune (webbrowser openseamap), everyting is blue with no differentiation of boat accessible or not. Are there possibilities to use osm data with desktop software or Android to get a “boat map” which shoes this differentation.
Its the most important outcome of an boat / seamap - to get information where it ist possible to enter by boat or not.
