What is PCOT?

PCOT is the PanCam Operations Toolkit - it's a piece of software originally designed to process information downloaded from the PanCam (Panoramic Camera) instrument on the Rosalind Franklin rover, part of the ExoMars project.

However, PCOT is capable of very much more than this. It can work with multispectral imagery from almost any source, and can function both as a program and a library. In particular, it can:

  • create spectra of points and regions
  • create spectral parameter maps (i.e. images created by performing calculations across multiple bands in the image - for example, dividing the 671nm by the 432nm band shows the presence of iron(III) compounds)
  • allow entirely arbitrary calculations on images, all while propagating uncertainty information on a per-pixel basis
  • add annotations
  • allow simple construction of operations through a visual "programming" language
  • perform pre-scripted operations through use as a Python library

and much more.

See the main PCOT website for details.
