<p class="moz-quote-pre" wrap="">One of the main issue I foresee
before doing any implementation is axis order. In the old epsg
file, geographic CRS use the longitude,latitude order, whereas
proj.db and the new code I've developped respect the axis order
declared by the authority, so in the case of
EPSG,latitude,longitude for geographic CRS.</p>
</blockquote>
<p>What about the following policy?</p>
<ul>
<li>"epsg" in "+init=epsg:4326" refers to axis order as declared
in the EPSG database.</li>
<li>For axis order as used in Proj.4, one of the following
choices:</li>
<ul>
<li>Define a new authority name, for example "+init=proj4:4326".</li>
<li>Or append a parameter to the code, for example
"+init=epsg:4326;axisOrder=lonlat". This proposal as been
discussed at OGC, but I don't think it became official
recommendation.<br>
