Simplest algorithm to cover a sphere

Question

What is the simplest algorithm for covering the surface of a sphere by walking. To word it another way, what would be the simplest algorithm a person could take to walk the surface of the earth?

Answer 1

Start at the South Pole, and walk north along the line of longitude that represents Greenwich Mean Time. Travel along this line of longitude via the following algorithm:

Take 1 step north.

Then make a complete circle along the corresponding line of latitude until you return to the pertinent line of longitude.

Then, rinse and repeat until you reach the North Pole.
