Scale 1:25 000 000 at 0° latitude Mercator projection Preliminary Pictorial Map of Io Atlas of Io 1:25,000,000 Topographic Series Ji 25M 2RMN, 1979 I-1240 This map was compiled from Voyager 1 and 2 pictures of Io. Placement of features is based on preliminary control information provided by M. E. Davies of the Rand Corporation, Santa Monica, California, and is probably accurate within 50 to 100 km. Feature names were approved by the International Astronomical Union in 1979. Airbrush representation is by P. M. Bridges.
