FAQ
N1 to PGM Conversion
What are N1 files?
N1 is the file extension of products from Envisat, a large Earth observation satellite of the European Space Agency (ESA). The letters in the name stand for the satellite itself: N1 for Envisat-1, while products from the older ERS-1 and ERS-2 satellites in the same family use E1 and E2. A file of this type contains the measurements of one instrument for one pass over the Earth, for example a radar image from ASAR, a color image of the ocean and land from the MERIS spectrometer, or sea surface temperature from AATSR. It also contains a description of the product and its quality. Many such files still lie in scientific archives, and they are used for research on oceans, ice, vegetation, and the atmosphere.
What are PGM files?
The PGM or Portable Graymap format is part of a package of open source graphics programs called Netpbm. Other Netpbm formats include PPM (Portable Pixmap) and PBM (Portable Bitmap), also known under the collective name of PNM (Portable Anymap). A PGM file includes a grayscale image, can work on a UNIX platform, as well as on Windows or Mac OS X, and can render a scope of up to 255 grayscale colors.
