Better Than Shadows. For Chief Cartographer Albert L. Nowicki of the Army Map Service, the traditional method of measuring lunar mountains by their shadows is not accurate enough. It works well only in the center of the moon's visible disk; off toward the edges it fades into uselessness. So the Army has turned to stereo photo-mapping in order to take advantage of the fact that the moon wobbles slightly but predictably at intervals of 3½ to seven years as it orbits the earth. This means that pictures taken of the moon at different times are like...
Arbitrary Altitude. The moon has no sea level to use as base elevation (its so-called seas are waterless plains), so Nowicki selected Mösting A, an easily identified crater near the center of the disk and gave the bottom of its crater the arbitrary altitude of 7,000 meters (23,000 ft.) to serve as reference for all other elevations. The finished map, which is 4.5 ft. in diameter, includes more than 5,000 surface features, giving elevations in hundreds of meters. One version of the map shows high and low areas in colors: the highest mountains...
