Windisp is a public domain, easy to use software package for the display and analysis of satellite images, maps and associated databases, with an emphasis on early warning for food security. WinDisp was originally developed for the FAO Global Information and Early Warning System. It allows users to:

  • Display and analyse satellite images
  • Compare two images and analyse trends in a time-series of images
  • Extract and graph trends from a number of satellite images such as during the growing season for comparison with other years
  • Compute new images from a series of images
  • Display tabular data in map format
  • Build custom products combining images, maps and specialised legends
  • Write and execute batch files to automate routine and tedious tasks
  • Build a customized project interface for providing users with detailed menus of available data for a country or a specific area

See a screenshot of Windisp.
