Digital elevation models of the lunar surface plots obtained in the course of photogrammetric processing of high resolution images received by the two narrow angle cameras (Narrow Angle Camera Left and Right) of the spacecraft LRO (Lunar Reconnaissance Orbiter). To control the obtained models, it is necessary to compare it with alternative data having spatial coordinates of the investigated surface, or with results obtained by other research teams. In particular of special interest for control and correction matrixes of heights, data represent the lunar laser altimeter LOLA. Figure 1 presents an example download LOLA RDR data. The subsequent figures show the control examples of a matrix of heights in data tracks LOLA in complex photogrammetric software PHOTOMOD®.
