Test 11U - With Overlaps
Truth topography: flat-topped cone with 20deg slope within a landscape of cones and craters.
Evaluation bigmap parameters: GSD = 1cm, Q = 200 (width=4m), centered at REGION.MAP, 966, 1005 (pixel/line location).

Test U - Operator-Induced Loss of Solution
The jump in behavior of Test U at iteration 51 is likely due to operator-interference. After 50 iterations an investigation was conducted on one of the maplets which contains the feature, maplet EE0057. During the investigation, the operator opened the landmark within Lithos and loaded the full image suite in order to view the high-emission-angle images. The images were then auto-eliminated as per the iteration sequence. Unfortunately, a comparison of the landmark OOT files between iterations 50 and 51 confirms that the solution degraded in several aspects. The image correlation dropped from 0.9+ to correlations as low as 0.217. The landmark overlap was also broken with EE0057 and EE0075 now showing 'below albedo correlation limit'. Further iteration did not recover these aspects with similar values displayed in the iteration 80 EE0057.OOT file.
