and content=* (values like sand, gravel, salt etc...). Combine
with landuse=commercial for the ones at depots for sale or
landuse=industrial or landuse=construction for the piles not for
sale to the general public. <br>
I know the wiki says these are for agriculture but it's easy to
extend (wiki) for other purposes. Bunker silos don't necessarily
have 3 walls to contain the bulk material, as in your example I
can't recognise any but essentially they are the same thing and
serve the same purpose. Some have ditches around them or are
pits, with the same purpose of containment and additionally
collecting run-off in wet conditions. <br>
Introducing another landuse or man_made tag seems ambiguous to
me, especially using stockpile as some might be empty short or
long term and then it would be to be defined as a pile or
stock_pile.<br>
Using the man_made tag is easy as they can be easily mapped and
incorporated in all kinds of larger facilties let it be depots,
factories, hardware stores, construction sites or just along
roads as maintenance stock depots.</font></p>

<div>How to tag?</div>

<div>They are called depots, and I guess landuse=depot could
include bulk materials. It's not a big step from containers.</div>

<div>I am unsure about a suitable value for depot=*. </div>

<div>In Dutch, its is called a "grond-depot", that is "ground
depot". Would depot=ground be a reasonable tag? Seems too easy
to be true...</div>
