[docs]def test_groundMapping(): r""" This test checks two points to determine if they are accessible for mapping or not. One point should be mapped, and one point should not be mapped. The inertial, planet-fixed planet-centered, and spacecraft body frames are all aligned. The spacecraft is in the -y direction of the inertial frame. The first point is along the line from the spacecraft to the origin. The second point is along the z-axis. The first point should be accessible because a.) the spacecraft is within the point's visibility cone and the point is within the spacecraft's visibility cone. The second point is not accessible because the spacecraft is not within the point's visibility cone and the point is not within the spacecraft's visibility cone.
