This is not sufficient to prove the earth is spherical. This method was used to 
calculate the diameter of the earth, already knowing that it was a sphere and 
the sun was very far away. To prove it was not flat, one has to use 3 
locations. Using just two only helps to prove the stupid flat earther's thought 
that the sun was much closer to the flat earth. 3 locations prove that it can't 
be flat because the angle changes too much over distance. It can be done in any 
direction but is easier to do North to South because time of day only needs to 
be at high noon and distance known.
