[Octave-bug-tracker] [bug #59444] [octave forge] (mapping) missing referenceSphere function

[anonymous]

Follow-up Comment #9, bug #59444 (project octave):

Sorry I just saw this, I will look into this more over the weekend.

I think JWE is jumping too fast (Not sure how a recorded missing function from
https://wiki.octave.org/Mapping_package is a bug).
Was there a specific need you had?


should be straightforward to create


*should*, I play this game too :)  

There is another missing function called rsphere (I have most of this
complete). The azimuth function need to accept referenceEllipsoids first,
before I can complete this.


What I suspect this function is doing is creating a wrapper for either the
'authalic' or 'eqavol' option of rsphere and reporting it.
https://en.wikipedia.org/wiki/Earth_radius#Authalic_radius

*Note* this is not confirmed.
The key understanding is there are many types of radii. 

There is the other component mentioned in comment #1
where the function is a classdef much like the missing map.geodesy.*
functions. This I do not know how to do, so I have left it. 

For comment #5
These values are interesting to be this exact of a value, and so many zeros.
Is this with using a format long? Planets with a flattening of zero ok (e.g.
Mercury), but not all.
