I'll use natural=grassland then. </span></span>

The areas I checked were always grass areas. natural=grassland might be better.

"Unimproved Pastures" are former landuse=meadows, they are overgrown with bushes and vegeation.</span></span><br></pre></div></div></div></div></div></div></div></div></blockquote><div dir="auto">Are you sure that <span style=""><span class="" style=""><span class="" style="font-family:Verdana, Geneva, sans-serif">Electrical Power Transmission Lines never have scrub</span></span></span><br></div><div dir="auto">growing beneath them?<br></div><div dir="auto"><br></div><div dir="auto"><div dir="auto">(I may be wrong, I am commenting from<br></div><div dir="auto">the other side of planet from place with a different climate)<br></div><div dir="auto"><br></div><div dir="auto">In general for such cases I would recommend not importing without review<br></div><div dir="auto">of such areas<br></div></div><blockquote class="tutanota_quote" style="border-left: 1px solid #93A3B8; padding-left: 10px; margin-left: 5px;"><div style="font-family: Verdana;font-size: 12.0px;"><div style="font-family: Verdana;font-size: 12.0px;"><div><div><div><div><div><div><div><div><pre><span style=""><span style="font-family:Verdana, Geneva, sans-serif" class="">2610: Fallow Cropland

Why not? These areas look like something between "Unimproved Pastures" and normal farmland. IMO it's fine to tag these as landuse=farmland, since they don't look too different.</span></span><br></pre></div></div></div></div></div></div></div></div></div></div></blockquote><div dir="auto">I expected scrub at least on some of them (but see disclaimer)<br></div><blockquote class="tutanota_quote" style="border-left: 1px solid #93A3B8; padding-left: 10px; margin-left: 5px;"><div style="font-family: Verdana;font-size: 12.0px;"><div style="font-family: Verdana;font-size: 12.0px;"><div><div><div><div><div><div><div><div><div><pre><span style=""><span style="font-family:Verdana, Geneva, sans-serif" class="">5200: Streams & Waterways

An seperate "Streams & Waterways" area is only used if the waterway has a certain size, so this does not incude small streams, only water areas on which water=river is applicable.</span></span><br></pre></div></div></div></div></div></div></div></div></div></div></div></blockquote><div dir="auto">It would be worth noting on wiki as it is quite surprising transformation.<br></div><blockquote class="tutanota_quote" style="border-left: 1px solid #93A3B8; padding-left: 10px; margin-left: 5px;"><div style="font-family: Verdana;font-size: 12.0px;"><div style="font-family: Verdana;font-size: 12.0px;"><div><div><div><div><div><div><div><div><div><div> <br></div><div>"Are these areas built as multipolygons with shared ways on the edges or assingle-way areas with overlapping borders?"<br></div><div><div>The landuses are single areas, with overlapping borders.

No. For each original value, I have looked at several objects to see what is meant in practice.
