The document discusses Tampa Bay marine mapping using OpenStreetMap and emphasizes the importance of up-to-date nautical data. It introduces OpenSeaMap as a free resource for nautical charting, along with examples of tagging for various maritime features such as beacons and lights. Additionally, it highlights tools and scripts for converting and managing this data for use in mapping applications.

Information-dense

8. Outdated
Paper & water don’t mix
Data is inherently non-portable
NOT SO GOOD

19. Beacons Buoys Lights Anchorages

20. Tagging Examples

21. seamark:type = beacon_lateral
seamark:name = 44
seamark:beacon_lateral:category = port
seamark:beacon_lateral:colour = red
seamark:beacon_lateral:height = 3
seamark:topmark:shape = cone, up
seamark:topmark:colour = red
Standard daymark

22. seamark:type = notice
seamark:name = No Wake
seamark:notice:category = no_wake
seamark:notice:function = restriction
Notice to boaters

23. seamark:type = light
seamark:light_minor:colour = red
seamark:light_minor:character = Fl
seamark:light_minor:period = 4
seamark:light_minor:range = 3
seamark:light_minor:height = 4
Light
