</div><br>I'm one of those rare people who use the GeoJSON CRS. I built a bunch of election results maps for Google over the last few years, and to speed up the JavaScript code a bit I used Spherical Mercator coordinates since those convert directly to pixels with a single multiplication. So I use this CRS in my GeoJSON files:</div>
<div class="gmail_extra"><br></div><div class="gmail_extra"><div class="gmail_extra"> "crs": {</div><div class="gmail_extra"> "type": "name",</div><div class="gmail_extra"> "properties": {</div>
<div class="gmail_extra"> "name": "urn:ogc:def:crs:EPSG::3857"</div><div class="gmail_extra"> }</div><div class="gmail_extra"> }</div><div><br></div></div><div class="gmail_extra" style>
with coordinates like these:</div><div class="gmail_extra" style><br></div><div class="gmail_extra" style> "bbox": [ 737758, 4231185, 2061653, 5957068 ]<br></div><div class="gmail_extra"><br></div><div class="gmail_extra" style>
I suppose it wouldn't make any real difference whether the crs object is in the standard or not, since I could just continue to use it in any case. Maybe if it weren't in the standard I would feel free to simplify it to:</div>
<div class="gmail_extra" style><br></div><div class="gmail_extra" style><div class="gmail_extra"> "crs": "urn:ogc:def:crs:EPSG::3857"</div><div class="gmail_extra"><br></div><div class="gmail_extra" style>
instead of all the extra structure it has now.</div><div class="gmail_extra" style><br></div><div class="gmail_extra" style>So I guess I don't have an opinion one way or the other on removing the CRS from the standard, just wanted to mention that I'm using it.</div>
