Marine Mapping in Tampa Bay

A talk about surveying nautical aids-to-navigation, landmarks, and features, and how to map them in OpenStreetMap.

Transcript

1. Tampa Bay Marine Mapping with OpenStreetMap Coleman McCormick @colemanm
2. Sailing Boating Fishing + Mapping osm.org/user/coleman @colemanm
6. CHARTS
7. GOOD Artistic Functional Information-dense
8. Outdated Paper & water don’t mix Data is inherently non-portable NOT SO GOOD
9. Daymarks
10. Soundings
11. Landmarks
12. Lights
13. Channels
14. How do I map these things?
15. OpenSeaMap Free & open nautical chart Uses the OpenStreetMap database openseamap.org
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
25. Editing Work!ow
26. Dogfooding our own software Fulcrum
28. geoJSON feature output: { "type": "Feature", "properties": { "seamark:type": "beacon_lateral", "seamark:name": "11", “seamark:beacon_lateral:category”: “starboard”, “seamark:beacon_lateral:colour”: “green”, "seamark:beacon_lateral:shape": "pile", "seamark:beacon_lateral:system": "iala-a" }, "geometry": { "type": "Point", "coordinates": [ -82.817967, 28.032795 ] } }
30. ./ogr2osm.py openseamap_markers.geojson openseamap_markers.osm http://svn.openstreetmap.org/applications/utils/import/ogr2osm/
33. Custom database tables from extracts with imposm http://imposm.org
34. imposm -U dbuser -d dbname -m spinnaker-mapping.py \ --read --write --optimize --deploy-production-tables \ florida.osm.pbf
36. Custom Electronic Charts
