IMPACT Toolbox

IMPACT Toolbox offers a combination of remote sensing, photo interpretation and processing technologies in a portable and stand-alone GIS environment, allowing non specialist users to easily accomplish all necessary pre-processing steps while giving a fast and user-friendly environment for visual editing and map validation. No installation or virtual machines are required.

Quick Data Visualization

  • Adjustable bands and stretch
  • Fast rendering with tiling approach
  • Data auto-load and refresh
  • Processing buttons for easy access
Map Visualization & Editing
  • Easy and efficient editing environment
  • Selection and recoding by:
    - class or cluster
    - single or multi polygon
  • 1 click edit
  • Class masking / showing
  • Customizable legend
  • On the fly .dbf file editing
Ground Truth Collection

Collection of ground truth data at local, national or global scale is now faster with a built-it feature editor supporting either systematic samples collection or wall-to-wall feature labeling.
  • Built-it degradation menu with identification of location, causes and intensity
  • Customizable legend
Version 5.0 beta

IMPACT v5 now runs on Windows, Unix and Mac operating system, allowing desktop and server installation. It comes with up to date processing and rendering libraries such as Python3, Gdal 3.1, ExtJs 7, Google Earth Engine Api. Link to thecnical documentation will be soon available in this page.
