Below is the technical information. The condition of these is very good. Kept rolled up. 4.2.1 Lunar Astronautical Chart (LAC) Series (Published by ACIC) Lunar Astronautical Charts Scale: 1:1,000,000 Projection: Mercator and Lambert Conformal Conic Sheet Size: 22” x 29” The LAC sheet layout which has often been used as a location reference in other lunar maps and publication provides for complete lunar coverage through 144 sheets. Forty-two nearside sheets have actually been published using earthbased telescopic photography and visual observations as basic sources. The charts are constructed on a Mercator projection (true scale at 11o 00’45’’) for charts in bands 0o to 16o N and 0o to 16o S; and, on a Lambert conformal conic projection in the following bands: 16o N-S to 32o N-S (standard parallels 21o 20’ and 42o 40’) 32o N-S to 48o N-S (standard parallels 21o 20’ and 42o 40’) 48o N-S to 80o N-S (standard parallels 53o 20’ and 74o 40’) The ACIC Selenodetic System (1965 was under development during the production of the LAC Series and later data sheets used this System for the selenographic control established from the measures of J. Franz and S. A. Saunders as compiled by D. W. G. Arthur and E. A. Whitaker in the Orthographic Atlas of the Moon. Gradients of major surface undulations were established by interpolating Schrutka-Rechtenstamm computations of J. Franz’s measurements of 150 moon craters. The varying control sources used during the course of compilation have sometimes resulted in mismatch of contour information between adjacent sheets. LAC charts portray lunar topography by shadient relief with a western illumination, approximate contours (300 meter interval), spot elevations, height differences between level features and crater depths. Background coloration is also used to indicate variance in reflectance of lunar areas under full illumination. Contours are omitted from many sheets (generally those covering limb areas) and the reverse side of some sheets contains a printing of the shadient relief portrayal, unencumbered with other chart details. Chart margin information includes an index of the series and qualifying and explanatory statements on the control, datum, nomenclature, relief portrayal, and elevation data contained. Feature names were taken from the International Astronomical Union nomenclature system. A dashed limiting line or dotted line is used to identify some features. The LAC Series was the principal source of available lunar cartographic information prior to the production of lunar maps from orbital photography. Its compilation included derivation of accurate local feature heights and depths through measurement of shadow images on source photography. However, use the earthbased vertical control and photography have not allowed definition of reliable regional elevation differences. By virtue of its scale, extent of coverage and topographic information contained, the LAC series continues to be of cartographic importance. The area of coverage provided by individual LAC sheets is reflected in Maps Index I(5). Chart No. Chart Name Edition & Date LAC-11 J. Herschel 1st Ed. Mar 1967 LAC-12 Plato 1st Ed.
