BirdsEye JNX Raster Map of Garmin (.jnx)

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.

JPEG 2000 Code Stream (.j2c)

The J2C file extension stands for JPEG 2000 Code Stream, a format defined in Part 1 of the JPEG 2000 standard. Developed by the Joint Photographic Experts Group (JPEG) from 1997 to 2000, J2C files utilize wavelet-based compression, supporting both lossy and lossless compression. This format is primarily used for high-quality image storage and transmission, offering superior compression efficiency and flexibility compared to the original JPEG standard. J2C files are often embedded within other file formats like JP2 for enhanced metadata support.
