<br><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Yahoo granted permission for us to trace from their imagery. yahoo<br>
imagery was available in josm and potlatch for quite some time. So<br>
I'd expect that your tracing of yahoo imagery is fine unless I<br>
misunderstand what you did.<br></blockquote><div><br>I knew it was fine at the time, while it licensed by CC-by-SA or CC-by.<br>I did not know it was OK by them to also publish it under a ODbL license.<br><br>This is why I thought both government data and traced data needed to be removed because of this license change.<br>
<br>So just to be clear, Nearmap are OK with CC-by-SA, but not with ODbL after a certain date ?<br></div></div>
