I once used a drone to map an inaccessible island in the Humber. The 
drone's camera can be pointed directly downwards, so I flew it around 
the island, keeping the high water mark in the centre of the frame. I 
then used the stored GPS track to update the map.

A practical solution to tidal beach areas is to map them as two areas 
with a common bound, that being the MHW nominal coastline. The areas 
above MHW can optionally carry the tag "tidal=no", but the areas below 
MHW should carry the tag "tidal=yes" and extend down to MLW(or MLWS or 
LAT). This is important for coastal walkers, who need to know what parts 
of an inviting beach may not be there on their return!

I am he! A seamark is any object of navigational importance. Onshore

are not a hazard to navigation. I suggest that these objects be tagged

Elsan is simply a trade name for a chemical toilet (likewise

It appears the intent of the elsan_point tag in the UK was the later (

Yes. This dates from the days when Elsan had the market to themselves in 
UK, so elsan became the generic term for any chemical toilet (This also 
happened with vacuum cleaners  Hoover - we still refer to any vacuum 
cleaner as ‘a hoover’). So the word elsan made its way onto the signage 
for chemical toilet emptying points.



---
Note the comparable USA term porta-potty refers to a portable chemical
toilet with no separate cassette (usually dragged by trailer to events,
construction
activity, or in camping areas without sewer access).



Note the spelling: “Porta Potti” is a trade name of the Thetford 
Corporation and refers their chemical toilet products.

e.g:

sandwich shops are a subset of fast food shops, as are fish  chip

Actually, OSM is more akin to an anarchic society - there is no

first raise the issue at the parish pump!

There is often a very a long time lag for coastline re-rendering,

Because of this long cycle time, it is a good idea to double check any

Re: [Talk-GB] How to tag marine lights on posts

2011-11-07 Thread Malcolm Herring
These are warning beacons to mark the line of reefs. The appropriate 
OpenSeaMap tagging would be:


seamark:type=beacon_special_purpose
seamark:beacon_special_purpose:category=artificial_reef
seamark:special_purpose_beacon:shape=pile
seamark:light:colour=whatever the colour of the light is
seamark:light:character=whatever the flashing pattern is
seamark:topmark:shape=if it has a topmark, the shape
seamark:topmark:colour=if it has a topmark, the colour

NB: these tags will only be rendered on OpenSeaMap (an overlay to the 
StreetMap).


man_made=beacon would be appropriate for the StreetMap, although I don't 
know whether this tag is rendered.

I encourage all riparian mappers to re-visit their efforts

If it is a river (as in your example), then waterway=river. Some 
waterways with xxx Navigation names are often mixtures of original 
rivers and cuts (canals) to circumvent unnavigable sections (weirs, 
rapids, etc). Use the waterway=canal on those sections.
