SUMMARY

The discussion centers on the feasibility of representing a vector in three-dimensional space using a single value derived from a spiral superimposed on a sphere. Participants argue that while it is theoretically possible to approximate a vector with one value by defining a spiral from the north pole to the south pole, this approach complicates the representation significantly. Key challenges include the need to specify additional parameters such as the spiral's diameter and the sphere's radius, ultimately leading to the conclusion that at least three values are necessary for accurate vector representation. The consensus is that while creative methods exist, they do not simplify the fundamental requirement of three-dimensional coordinates.

Does this new convention "avoid reference to elevation?"
Not sure if you still find this relevant, but yes, it would define elevation. It would complete reference to a 3rd dimension after (1st-D) in terms of no. of "orbits" and (2nd-D) in terms of % of distance from NP to SP since I'm assuming that we're still in a sphere of unitary size (r=1). In order to express 3D entirely within the realm of "orbits" it might be a good idea to express the 3rd-D reference in terms of total distance along the "orbits'" path from NP to SP since we would effectively be defining the radius of the sphere beyond r=1.
