Seamark tagging
Bridges
The tags defined on this page will render in various nautical charts (zoom-level 16 and higher).
An other example: Navigable Waterways, Europe (zoom-levels 1-13)
For routing purpose, the tag should be placed on the waterway beneath the bridge.
This page defines tags for the attributes of bridges.
Type | S100 code | seamark:type | Definition |
---|---|---|---|
Bridge | BRIDGE | bridge | A structure erected over a body of water to provide a roadway for vehicles, pedestrians or to carry utility services. |
Categories
Category (CATBRG) | seamark:bridge:category | Note | Definition | Photo |
---|---|---|---|---|
Fixed bridge | fixed | preferred category. If known, add seamark:bridge:clearance_height=* | A bridge having permanent horizontal and vertical alignment. | |
Opening bridge | opening | preferred category. If known, add seamark:bridge:clearance_height_closed=* | A bridge that is closed when set for carrying road traffic and open when set to permit marine traffic to pass through the waterway it crosses. | |
Lifting bridge | lifting | preferred category. If known, add seamark:bridge:clearance_height_closed=* and seamark:bridge:clearance_height_open=* | A movable bridge (or span thereof) which is capable of being lifted vertically to allow vessels to pass beneath. | |
Swing bridge | swing | opening, if known, add seamark:bridge:clearance_height_closed=* | A movable bridge (or span thereof) which rotates in a horizontal plane about a vertical pivot to allow the passage of vessels. | |
Bascule bridge | bascule | opening, if known, add seamark:bridge:clearance_height_closed=* | A counterpoise bridge rotated in a vertical plane about an axis at one or both ends. | |
Pontoon bridge | pontoon | ambiguous: might be fixed or opening | A fixed floating bridge supported by pontoons. | |
Drawbridge | drawbridge | opening, if known, add seamark:bridge:clearance_height_closed=* | A general name for bridges of which part or the entire span of the bridge may be raised or drawn aside to allow ships to pass through. | |
Transporter bridge | fixed, if known, add seamark:bridge:clearance_height=* | A bridge that has towers on each side of the waterway connected by a girder system on which a carriage runs. | ||
Foot bridge | footbridge | ambiguous: might be fixed, opening, lifting | A bridge structure used only for pedestrian traffic. | |
Viaduct | viaduct | fixed, if known, add seamark:bridge:clearance_height=* | A long bridge consisting of a series of beams, spans or girders (of steel, timber or concrete) supported on towers or piers and used to carry a road, railroad, etc. | |
Aqueduct | aqueduct | fixed, if known, add seamark:bridge:clearance_height=* | A bridge supporting an artificially elevated channel, for the conveyance of water. | |
Suspension bridge | suspension | ambiguous: might be fixed or lifting | A fixed bridge consisting of either a roadway or a truss suspended from two or more cables which pass over towers and are anchored by backstays to a firm foundation. |
Clearances
Attribute | seamark:bridge:<attribute> | Value type | Definition |
