The Flexible Image Transport System (FITS) file format is a digital file format used primarily in astronomy for storing, transmitting, and analyzing scientific images and data. Developed in the late 1970s, FITS was designed to provide a standard for the interchange of astronomical data, facilitating the sharing and analysis of data among astronomers and researchers worldwide.
The PNM (Portable Any Map Image) file format is a subset of the broader Netpbm format, designed for storing various types of digital images. It acts as an umbrella term for three specific types of grayscale, color, and black-and-white images, represented by PBM (Portable Bitmap), PGM (Portable Graymap), and PPM (Portable Pixmap) formats respectively. PNM files are known for their simplicity and ease of conversion to other image formats.
