<div dir="ltr">I am happy to see an axis order parameter in the
proj lib. In the shipped epsg file there are already a few axis
order settings, but a few hundreds are missing. As this also
effects commonly used codes such as 4326 (which has, by crs
definition, <span

worthwhile to revise the epsg file regarding the axis order
parameter.

Hello Martin<br>
<br>
I don't know if Proj.4 provides axis order information directly.
However this information is provided in the GeoAPI wrappers for
Proj.4. Since those wrappers are in public domain, they could be
copied in any project under any license of your choice. The file is
there:<br>
<br>
<a class="moz-txt-link-freetext" href="http://svn.code.sf.net/p/geoapi/code/trunk/geoapi-proj4/src/main/resources/org/opengis/wrapper/proj4/axis-orientations.txt">http://svn.code.sf.net/p/geoapi/code/trunk/geoapi-proj4/src/main/resources/org/opengis/wrapper/proj4/axis-orientations.txt</a><br>
<br>
For example the line "ne:" lists the EPSG codes of all geographic
CRS using the "North, East" axis order. The line "sw,ne" lists the
EPSG codes of all projected CRS using the "South,West" axis order
and based on a geographic CRS using the "North,East" axis order.<br>
<br>
Note that this directory provides also other information that may be
useful, like a mapping from Proj.4 projection names to EPSG and OGC
projection names.<br>
