Elevations increase westward across the map from about 2.5 km in Oceanus Procellarum to more than 5 km in the highlands west of Orientale. The terrain is exceedingly rugged outward from the Montes Cordillera around Orientale but becomes increasingly smooth in the outer facies of the ejecta and beyond the ejecta deposits around the basin. Eight large older multiringed basins surround Orientale in this region of the Moon. With the exception of Orientale, only those adjacent to Oceanus Procellarum have their centers filled or partly filled with mare basalt. All attributes created during the creation process were verified by displaying the lines in both the database and the spatial coverage, but no formal tests were performed.
Line geometry is topologically clean.
