Is there any relations between the "1D axial symmetry" and "spherical coordinate"

Hello everyone. I am quite confused by the "1D axial symmetry geometry". To my understanding, "1D axial symmetry geometry" actually represents the spherical coordinate. For example, line in "1D axial symmetry geometry" represents arbitrary radius of a sphere , so if I can know the distribution along this line , I also know the distribution in the sphere.
I need to do some integration over a whole sphere domain rather than the line. so I define it like this: intop1(4*pi*r^2*f(r)). f(r) represents certain distribution along the line , intop1 is the symbol of line-integration. I can't get the right answer in this way.
I also noticed that the "revolution 1D" would result in a circle rather than a sphere, and the three vectors of this geometry are r, z ,phi ,which are identical with "2D axial symmetry". So I doubt by choosing "1D axial symmetry geometry", I can't extend the data from line to sphere?
Can you give me some advice ,please?
