For every globe we would always need a geodesic system. Even if it is the Mars, we need to know where are the poles, where is the 0 Meridian, etc. Refering to these seems to make most sense.<div><br></div><div>Which does not mean that we should let the user decide if they want WGS84 or Ares Prime 0, or Selenographic system etc. -- the editor should merely choose &quot;Earth&quot;, &quot;Mars&quot;, or &quot;Moon&quot; respectively. (Names are made up, I could actually not figure out what the usual geodesic systems are).</div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hey,<br><div><div class="im"><br><blockquote>Why use Q2 (&quot;earth&quot;) as the glob, and not Q215848 (&quot;WSG84&quot;)? That would be a lot<br>

clearer, I think.<br></blockquote><br></div>Since WGS84 implies Earth, this works for Earth. Is such an implication always present though? What if I want to describe a location on some random planet - I suspect you&#39;d have to specify some system and the globe. If this is the case, we should not omit the globe.<br>
