OK, so here is the Google Earth image just for clarity:<div><span class="Apple-style-span" style="font-family: Tahoma; font-size: 11px; white-space: pre; -webkit-border-horizontal-spacing: 2px; -webkit-border-vertical-spacing: 2px; "><a href="http://img353.imageshack.us/img353/9470/gearthbx4.png">http://img353.imageshack.us/img353/9470/gearthbx4.png</a></span></div>
<div><span class="Apple-style-span" style="font-family: Tahoma; font-size: 11px; white-space: pre; -webkit-border-horizontal-spacing: 2px; -webkit-border-vertical-spacing: 2px;"><br></span></div><div><span class="Apple-style-span" style="font-family: Tahoma; font-size: 11px; white-space: pre; -webkit-border-horizontal-spacing: 2px; -webkit-border-vertical-spacing: 2px;">The lower three bridges are tagged as layer 1. I tagged the upper bridge as layer 2 since it eventually crosses over two of the layer 1 bridges. OK so far (I assume). But when viewed in JOSM I get this:</span></div>
<div><span class="Apple-style-span" style="font-family: Tahoma; font-size: 11px; white-space: pre; -webkit-border-horizontal-spacing: 2px; -webkit-border-vertical-spacing: 2px;"><a href="http://img353.imageshack.us/img353/599/josmby9.png">http://img353.imageshack.us/img353/599/josmby9.png</a></span></div>
<div><span class="Apple-style-span" style="font-family: Tahoma; font-size: 11px; white-space: pre; -webkit-border-horizontal-spacing: 2px; -webkit-border-vertical-spacing: 2px;"><br></span></div><div><span class="Apple-style-span" style="font-family: Tahoma; font-size: 11px; white-space: pre; -webkit-border-horizontal-spacing: 2px; -webkit-border-vertical-spacing: 2px;">Obviously that upper, layer 2, bridge goes under the layer 1 bridge. It also goes under a non-layer tagged (layer 0) road just off image where my red gpx track can be seen.</span></div>
<div><span class="Apple-style-span" style="font-family: Tahoma; font-size: 11px; white-space: pre; -webkit-border-horizontal-spacing: 2px; -webkit-border-vertical-spacing: 2px;"><br></span></div><div><span class="Apple-style-span" style="font-family: Tahoma; font-size: 11px; white-space: pre; -webkit-border-horizontal-spacing: 2px; -webkit-border-vertical-spacing: 2px;">My question is ... Does JOSM not bother to actually correctly render items with respect to layer? I have yet to upload the changes to the data to see if Mapnik or Osmarender renders them correctly, but I will. (I was more concerned with what JOSM was showing me.) If JOSM DOES take the layer tag into consideration, then any ideas on what is happening here?<br clear="all">
</span><br></div><div><br></div><div>Secondly ... First, no I am not using Google to trace roads. You'll notice the image shift can be a bit confusing. But I am wondering. Since Google does not actually have any road data in Korea, there is no way I could infringe on the copyright of "their" road data, but ... since I would just be using their image, then shifting it to match my tracks, and then tracing over other roads on the shifted image ... </div>
<div><br></div><div>Wouldn't this be OK under the fair use clause of intellectual property law, especially since I am not actually making a <span class="Apple-style-span" style="font-family: -webkit-sans-serif; font-size: 12px; line-height: 19px; ">derivative work of any existing road data or an image from existing image data?</span></div>

I may have missed the relevant chapter and verse.</span></div>
