Solution is surprisingly good given this is from a single sun angle (see Data Set above). However there are many details that SPC doesn't get right, such as an apparent oscillation away from the boulder, and a dip in the E-W transit on the right of the plot. The dip could be due an artifact from nearby topography, but it is not seen in the other Sun angle tests. Notice that the height of the boulder in this solution is always less than the truth, and the surrounding topography is often greater than the truth. |
Data Set
Notice that one of the s/c zenith angles is missing. For whatever reason that image didn't correlate well and was excluded from the solution. This did not happen on all landmarks in this test, but it did happen for more than half.
