PANCROMA™ System Requirements

PANCROMA™ runs on all popular [PANCROMA pan sharpening]Windows® operating systems, including Windows 8, Windows7, Windows Vista, Windows XP and Windows NT.

Landsat data files are very large. Each of the three band files needed for pan sharpening is about 60MB in size. The panchromatic file is even larger: about 250MB. Several temporary files of similar size are required to perform the necessary transformations. When you are done pan sharpening you may have an RGB file as large as 850MB to save and subsequently reload.

As a result, pan-sharpening uses a lot of computer resources and a more powerful computer will of course perform the computations faster than an older and slower machine. The amount of installed RAM in your computer has the largest affect on processing times, along with the amount of RAM in your graphics card. Computer requirements are as follows.

Minimum system requirements¹:

  • 1.6 GHz Pentium Processor

  • 256MB SDRAM

  • 32MB Graphics Card

  • Windows XP/NT Operating System

Recommended system configuration²:

  • 2.66 GHz Intel Core™ Quad CPU

  • 4096MB SDRAM

  • 512MB Graphics Card

  • Windows Vista or Higher Operating System

¹Note: Systems with 256MB RAM will be able to pan sharpen full-size Landsat data sets. However, ELIN an other utilities may not work. Also, processing speeds will be slow. Also, the resulting RGB pan sharpened image may be too big for your computer to display. (You can always choose not to display the image). See the article on processing huge datasets at

²Note: This configuration will allow processing at the fastest speeds.
