0 degrees latitude seems to be the South Pole, and 180 degrees latitude seems to be north pole. I would expect 0 to be at the equator, 90 to be north pole, -90 to be south.
0 and 360 degrees longitude seems to be on the opposite side of Greenwhich, increasing as you go east. I would expect this to be at Greenwich, increasing as you go east until hitting 180 around international date line, and decreasing as you go west until hitting -180 at the same location.
