+X and +Y directions need latitude coordinate #16

Closed MBARIMike closed 9 years ago

MBARIMike commented 9 years ago

In subsection "The geocentric coordinate system"

Perhaps add "at equator", or "in equatorial plane" for direction of +X and +Y axes. Also, +Y is at 90 degrees east, correct?

In section 4.1 ? Yes, this would help although not strictly necessary since the sentence before just establishes that the origin is at the center. What about: "In the equatorial plane, the +X direction points to 0 degrees longitude and the +Y direction to 90 degrees longitude east. The +Z direction points to the north pole."
