<p>Still trying to figure this out. This is using PROJ6, btw. Based
on another thread, there are two ways of specifying EPSG 4326:</p>
<p>+proj=longlat +datum=WGS84</p>
<p>and <br>
</p>
<p>+proj=longlat +datum=WGS84 +type=crs</p>
<p>The former is PJ_TYPE_OTHER_COORDINATE_OPERATION and the latter
is PJ_TYPE_GEOGRAPHIC_2D_CRS. I don't understand the difference.
How can the first be an operation? What's it doing? And why does a
CRS not work with proj_lp_dist?<br>
