I am trying to define a custom CRS based on Equal Earth Projection (As described here) in QGIS (Settings >> Custom Projections >> + [
Add new CRS] >> Entering Proj String [
+proj=eqearth +datum=WGS84 +wktext] >> OK).
The validation of the Proj String goes fine; however, after pressing OK it gives the following error message.
Cannot save' * Generated CRS (+proj=aeqd +lat_0=0 +lon_0=0 +x_0=0 +y_0=0 + datum=WGS84 + units= m + no_defs)' — this Proj string definition is identical to ESRI:54032. Try changing the CRS definition to a WKTformat instead.
I thought that probably ESRI:54032 and Equal Earth maybe the same thing. But when I change my map projection to ESRI:5432, it does not looks like Equal Earth Projections.
Are the Equal Earth and ESRI:54032 the same? If not, how can I define the Equal Earth projection in QGIS?
I am using QGIS 3.12 (64 bit) on Windows 10. Detailed specification about QGIS and related libraries is here.
A similar question already exists but neither the question nor the answers address the problem I have described.
