The FITS (Flexible Image Transport System) file extension is widely utilized in the field of astronomy for storing, transmitting, and manipulating scientific data and images. Originating in the late 1970s, FITS was developed by NASA and the International Astronomical Union (IAU) to standardize the format for astronomical data. Its primary use is to archive astronomical images, spectral data, and other multidimensional data arrays, enabling efficient data interchange among scientists and astronomers. FITS files are known for their ability to store metadata and large datasets, making them essential for detailed scientific analysis and long-term preservation in research environments.
The PNM (Portable Anymap) file extension, developed by Jef Poskanzer in the 1980s, stands for Portable Any Map. It is an uncompressed raster graphics format designed for portable image storage and exchange, encompassing three sub-formats: PBM (Portable Bitmap), PGM (Portable Graymap), and PPM (Portable Pixmap). PNM files store image data in plain text or binary format, ensuring easy usage across different platforms and applications. This format is widely supported by various image editing software and is valued for its simplicity and lossless compression.
