<div>Yes, I'm now seeing what you mean, especially after relating it to Holsworthy, but still trying to visualise how it would work, especially for somewhere like that, that has both ground forces & also aviation on the same base? Another prime example would be <a href="https://www.openstreetmap.org/relation/6145740#map=10/34.4681/-116.2189">https://www.openstreetmap.org/relation/6145740#map=10/34.4681/-116.2189</a>.</div><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_quote">As a general rule, I think just "army base" is sufficient for a hypothetical multi-function base occupied by an army service. However, I note from Wikipedia's discussion of that base:</div><div class="gmail_quote"><br></div><div class="gmail_quote">"Holsworthy Barracks (ICAO: YSHW) is an Australian Army military barracks [...] is part of the Holsworthy military reserve, which is 22,000-hectare (54,000-acre) training area and artillery range for the Australian Army, [...] Holsworthy Military Airport is also located in the reserve."</div><div class="gmail_quote"><br></div><div class="gmail_quote">It calls out "Holsworthy Barracks", "Holsworthy military reserve", and "Holsworthy Military Airport" as separate places. Wikipedia seems to think these are different things, and it seems like we should have tagging that can describe the differences. "Holsworthy Military Airport" sounds like a perfect example of an army base that is performing air component functions. <br></div></div></blockquote><div><br></div><div>Yep, agree with you entirely! Rather than just being tagged
landuse=military + military=barracks as it is now, the whole area should be landuse=military, with the built-up area being military=base, the airfield military=airfield, & the bush military=training_area + military=range + military=danger_area! - can we mark all three on one area?<br></div><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_quote">Don't take this as criticism, as I fully support the proposed military_service tag. </div></div></blockquote><div><br></div><div>Don't worry, I'm not! This is all great stuff, as it helps to make sure we get it right from the start, rather than realising
several years later that we really should have ... :-( Got to say, though,
that going through the existing 9000, I'm thinking probably mostly
incorrect, military=barracks is going to be a <i>bbbiiiggg</i> job! - MapRoulette challenge perhaps?</div><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_quote">But -- I can already envision the mis-tagging that may occur the first time a mapper encounters a military base that "quacks like a cow" and goes to the wiki and there isn't an obvious way to tag these differences beyond the "name" tag. We have an opportunity here to make the tagging more fully descriptive to indicate both the service that operates a base as well as the overall military purpose for bases that are specialized.</div></div></blockquote><div><br></div><div>I did mention earlier in reply to one of the comments that (previously base=) military_service=yes / unknown would be OK if you can't work out what's in there, so that should hopefully cover that problem?<br></div> <br></div><div>Thanks</div><div><br></div><div>Graeme<br></div><br></div></div>
