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 JBG file extension stands for Joint Bi-level Image Group, a format developed for efficient lossless compression of binary images, primarily used in fax transmissions. Introduced by the Joint Bi-level Image Experts Group, JBG files store 1-bit raster images and offer superior compression compared to older standards like CCITT Group 3 and 4. Although initially popular for fax machines, the format has largely been superseded by JBIG2, which provides even better compression.
