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></blockquote><div><br></div><div>Bunker silo could be stretched to include these piles of bulk material. But they are formed on the terrain as needed, for different bulk materials. So I can't pinpoint and tag individual bunker silo's, and I can't tag the contents. That's not necessarily a problem, but again, stretching thngs. </div><div>As for the landuse, it's not commercial or industrial, and the land itself is not a construction site. Maybe industrial could be stretched to include </div><div>common storage for various bulk materials for various current and future municipal projects in the municipal area? </div><div><br></div><div><br></div></div></div>
