The JNX file extension stands for "BirdsEye JNX Raster Map" and is used by Garmin devices like the Alpha 100 and Montana 650 for navigating terrain. It contains a large raster map divided into small tiles for optimized rendering and includes an encrypted unit ID for the specific Garmin device. JNX files are part of the BirdsEye subscription service, allowing fast map rendering and supporting up to 5000 tiles per level. However, they are device-specific and cannot be created from other raster maps.
The CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image file format, developed by the United States Department of Defense in the mid-1980s, is a standard for storing raster (bit-mapped) image data, typically black-and-white. It ensures efficient data interchange and retention of orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images. This standard was part of the broader CALS initiative aimed at improving electronic publishing and data management within the federal government.
