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 Portable Floatmap (PFM) file format, also known as Portable FloatMap, is an image file format designed to store High Dynamic Range (HDR) images using floating-point values. Developed in the spirit of the Portable Pixmap format, PFM files contain image data with resolutions and byte order specified in the header. This format is particularly useful for applications requiring precise image data, such as computer graphics and image processing. PFM has been widely adopted in the IT industry for its ability to handle a wide range of pixel values beyond the standard 0-255 range, making it ideal for HDR imaging and other advanced visualizations.
