FAQ
DIM to PGM Conversion
What are DIM files?
DIM (Digital Image MAP) is a metadata-driven format for satellite imagery, developed by the French space agency CNES together with SPOT Image to describe products from the SPOT and Pléiades missions. A dataset consists of an XML file with the .dim extension and one or more image files stored beside it, usually as GeoTIFF or JPEG 2000 rasters, while earlier versions used BIL and TIFF files. The XML document describes the product identification, acquisition date and time, sensor and satellite parameters, geometric processing level, coordinate reference system, band names and order, radiometric calibration values, sun and viewing angles, and the image dimensions. Related files may hold preview images, quality masks, and rational polynomial coefficients for sensor model correction. The format is applied to panchromatic, multispectral, and pan-sharpened scenes at several processing levels, from primary to orthorectified products, and the .dim file acts as the entry point to the whole dataset.
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.
