Trust every image, get every insight

When you rely on remote sensing information for high level decisions, you want to leave as little room for error as possible. That’s why accurate and precise data is extremely important in deriving the correct information.

With our range of calibration and correction measures, we help you consistently achieve the highest levels of image – and data – quality.

The following methods successfully transform raw data into physical quantities – accurately positioned on the earth:

  • Geometric calibration
  • Radiometric calibration
  • Atmospheric correction

We then validate the end-products and continuously monitor their quality to detect anomalies. The results help us to investigate alternative processing methods and improve our products. 

iCOR, for atmospheric image correction

iCOR (previously known as OPERA) is an atmospheric correction software which is available through the ESA Sentinel Application Platform (SNAP) for the atmospheric correction of Sentinel-2 and Landsat-8  data.
You can download the iCOR tool for free. After download and installation you can run the tool as a plugin in SNAP. iCOR was developed through funding from the Belgian Science Policy, The European Space Agency and the European Commission.


Every operational sensor exhibits perturbations to the ideal sensor model. These are caused by anything from optical distortions to exterior orientation inaccuracies.

Vicarious calibration uses stable, mostly natural objects for calibration. VITO develops vicarious Cal/Val methodologies for optical instruments and tunes these algorithms in operational systems.

In remote sensing, signal disturbance by atmospheric influences is commonplace. Reflected light is scattered and absorbed by molecules and aerosols in the atmosphere, modifying the appearance of objects.

Applications and Data Products & Services Used

  • Remote sensing in agriculture
  • Empowering infrastructure management
  • Vegetation
  • Water and coastal management

Achieving global food security has been high on the political agenda for years. It was included in the first of eight UN Millennium Development Goals “to eradicate extreme poverty and hunger”.
This requires global, independent, timely and qualitative information and monitoring.

Roads, bridges, tunnels, waterways, ditch systems, dikes, sluices, coastal dunes, sewer systems, buildings, power lines, wind turbines, PV installations… In order to keep the engine of economic activities running smoothly, maintenance is critical.
Infrastructure maintenance requires recurrent inspection. Remote sensing is ideal for this task without stopping traffic.

How much pressure does our planet endure and how can we minimize it? Land is an essential natural resource - for humanity and all terrestrial ecosystems. But while resources are strictly finite, human demands are not. Today, this leads to events such as deforestation, drought and the loss of wildlife . Both public and private organizations play a crucial role in the preservation of our ecosystems, where understanding is the first step.

The effects of pollution, erosion and climate change on coastal areas are closely gauged and monitored. The related water management, flood risk assessment and different aspects of coastal management rely on measurements and modelling practices that are often faced with complicated accessibility issues.
