Historical information
This set of map prints was assembled as a training aid. The collection is a complete set of individual color prints of each colour used on the final printed maps for each map Joint Operations Graphic (JOG) JOG Ground and JOG Air versions. This map series was produced in two versions to help coordinate military Ground Operations and Air Operations. The ground users required that heights and measurements were in Metres, whilst air users required height information in Feet for altimeters. The Air Version also contained more Aeronautical information including safe flying height information called Maximum Elevation Figures (MEF). Later printing of JOG incorporated printing in just four colours Cyan, Magenta, Yellow and Black (CMYK). Item 6421.1 is an example of a JOG Ground and item 6421.2 is an example of its matching JOG Air version.
