Example terrains (in columns) showing all database features for each catalog examined in this work. The reference database is in the top row. Scale bars are 90, 120, and 450 km in the left, center, and right columns, and the significant reduction in scale in the right column is meant to illustrate how the algorithms work on large features. The left column is in Mare Tranquillitatis, the center is the nearside highlands, and the right is the farside highlands.
