I've an OSM compatible dataset that helps me to spot landfills. Older<br>
ones are already covered by grass and/or trees.<br>
<br>
IMHO could be useful to save landfill locations for a future possible use.<br>
Does it make sense tag the ones with surface alterations with level=-1 ?<br>
<br></blockquote><div><br></div><div><br></div>IMHO, landuse is not stacked, at least not in a case like this (there may be some exceptional situations, eventually). The fact that the landfill is overgrown still makes it a landfill, and all the toxic stuff is still there, just covered by a thin layer of soil and vegetation.<br><div><br></div><div> </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">
Or shall I consider landuse=landfill as a functional tagging, hence<br>
tagging them abandoned:landuse=landfill?</blockquote></div><div><br></div><div><br></div><div>that's a good question. Landuse is not completely consistent. There are a few landuses like quarry, landfill and even "harbour" which do not integrate well with the other landuses because these mentioned are typically used _also_ for features (i.e. if you split a landuse=quarry, you will have 2 quarries, opposed to e.g. landuse=residential, which simply says this area is used as residential area, and if you split it, the meaning remains the same, i.e. it is a property about the use of land).</div><div><br></div><div>A possible solution would be the introduction of feature tags for these outliers, e.g. man_made=quarry, man_made=landfill / waste_dump, seaway=port / cargo_port / fishing_port etc.<br></div><div><br></div><div>Cheers<br></div><div>Martin<br></div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div></div>
