(This is a duplicate/cross-port of my question I asked at GIS Stack Exchange, where it was suggested I ask this question here again — I apologise if this is not the right community)
In pyproj, I defined/loaded projection IAU 39916. This has the name “Earth (2015) / Ographic / Equirectangular, clon = 180”. (I was looking for an equirectangular projection for representing an area on both hemispheres around the antimeridian.)
What does “ographic” mean here? In this context, it cannot mean orthographic, because the projection is equirectangular and not orthographic. Google Search gives me results on converting between “ographic” and “ocentric” (example from this site), but I have not found what those actually are. Is it related to geocentric and geodetic latitudes in any way?
In : from pyproj import CRS In : crs = CRS.from_authority("IAU_2015", 39916) In : print(crs.name) Earth (2015) / Ographic / Equirectangular, clon = 180
