MIL-STD-2402, STANDARD PRACTICE FOR MAPPING, CHARTING, AND GEODESY SYMBOLS FOR GRAPHIC PRODUCTS (21 APR 1995)., This standard defines Mapping, Charting, and Geodesy (MC&G) symbology for the Defense Mapping Agency (DMA) graphic (hardcopy) products. This is one of two military standards that document symbology for DMA products. Symbology associated with DMA Vector Products (those in Vector Product Format), are found in Mil-STD-2412, Vector Product Format Symbology.
