According the comment in EquidistantCylindrical:
* "standard_parallel_1" is used by ESRI and Synder
* "latitude_of_origin" is used by EPSG and remotesensing.org
I will add alias on the 2.4 branch.

We didn't found any indication on the web about ellipsical
EquidistantCylindrical. If someone has some guidance about what should be the
appropriate calculation, we could add it.
