Sometimes there is a a 'No Trespass" or "No Hunting" sign. But every local jurisdiction is different, and who does what where and when can be a fairly complex situation, a combination of both statute (laws) and custom / etiquette <http://fwp.mt.gov/fishing/guide/access/streamAccess.html>. If folks abuse the custom, it usually becomes statute. For instance, Montana allows public right of way down and along<http://fwp.mt.gov/fishing/guide/access/streamAccess.html>most flowing, non-intermittent waterways (below the high water line) for recreational purposes <http://fwp.mt.gov/recreation/ethics/riverRecreation.html>. In Washington State, similar rules apply to access along salt water, in the intertidal zone. New York City has privately owned public parks<http://www.nyc.gov/html/dcp/html/priv/priv.shtml>, where there has been disputes between neighbors and corporations about access times, activities permitted, etc. The point being, is that every locale is going to have features (and combinations of features) to give contest to some user's activity or use. And for that individual or community of users, if that feature(s) can't be added or isn't present, the map is 'broken'. If my purpose is to portray kayaking or combing routes along the washing coast, the low and high water line are critical - not having these simple pieces of information can actually be dangerous to the person viewing the map, because of the nature of the shoreline. If it's hiking / snow shoeing, while 10 ft contours would be overkill, the 500ft, 1000ft, 1500ft, 2000ft, etc. are critical because weather warnings are broadcast according to those levels. In the urban areas of Seattle, major areas are referred to by which 'hill' they are on. The first line in the OSM Wiki says *"Welcome to OpenStreetMap, the project that creates and distributes free geographic data for the world. We started it because most maps you think of as free actually have legal or technical restrictions on their use, holding back people from using them in creative, productive, or unexpected ways."* Adapting the some parts of the map content local conditions would seem to meet this philosophy, but I have been detecting a refrain that if it doesn't fit some current 'x-y-z' tradition / theme, go do it 'elsewhere'.
