<p>Hello all</p>
<p>Thanks to those who replied. So we have so far:</p>
<ul>
<li>pyproj for custom CRS building capability<br>
</li>
<li>spatialreference.org for output and for extracting axis
information directly from the JSON file</li>
<li>rasterio (based on GDAL if I'm understanding right?)<br>
</li>
<li>Digital Coast Data Access Viewer grabs some projection
information from PROJJSON</li>
</ul>
<p>More specifically, we would like to clarify which implementations
exist in addition of PROJ. Is the following correct?</p>
<ul>
<li>pyproj, spatialreference.org and rasterio use PROJ for
reading/writing PROJJSON.</li>
<li>spatialreference.org and Digital Coast Data Access Viewer grab
information directly from the PROJJSON file, which could be seen
as a kind of implementation.</li>
</ul>
<p>Thanks,</p>
<p> Martin</p>
