PNM Raw in het kort
PNM Raw
PNM survived because engineers kept needing a no-drama raster family for scripts, fixtures, codecs, and image-processing experiments where the format should not be the hard part.
FITS in het kort
FITS
FITS became a durable scientific standard because observatories, spacecraft, and analysis tools needed a stable interchange format that outlived individual instruments and software stacks.
