FAQ
ERS to PGM Conversion
What are ERS files?
ERS is the header file of the ER Mapper raster format, developed for the ER Mapper image processing software, now part of ERDAS. A dataset of this type consists of two files: a plain-text header with the .ers extension and a binary data file with the same base name and no extension. The header describes the data in a structured, readable form, including the number of lines, cells, and bands, the data type of the pixels, the cell size, the byte order, and the coordinate system. The data file stores the pixel values themselves, without compression. The format is used for satellite and aerial imagery, geophysical grids, and elevation models, particularly in mining, exploration, and remote sensing, and it is recognized by many mapping and geoscience programs.
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.
