Image processing to determine the surface and atmospheric features


Satellite images and geophysics acquisition: high-potential, high-resolution images

Satellite observation of the Earth is a tool that enables:
● Analysis (mapping, detecting changes, etc.)
● Inventory creation (e.g. of land use)
● Assistance with forecasting (e.g. for farming), or
● Simulation (of natural risks, etc.).

Today, a large proportion of satellite images can be accessed free of charge.
To complement this, we propose data acquisition by drone or light aircraft enabling the areas of interest to be analysed at different resolutions.

Technical and discipline knowledge to achieve optimal processing

In remote sensing, knowledge about sensors and processing techniques is crucial, as is discipline-specific knowledge, in order to put all the data into an applications context.

Platforms that allow satellite image access and processing online enable users to access images directly and process data in the Cloud, with performances far superior to the standard methods. Thanks to the interactive nature of these technologies, we are rolling out powerful tools and continuously maintaining the applications.

To meet a client’s requirements, we look for the data source that best suits the topic in question, and the processing space that will be most effective and deliver maximum value.

Artificial intelligence to enhance processing of these mass data

Now that thousands of databases and image repositories have been made available, and processing techniques have evolved, the use of artificial intelligence to refine this information has become a major stake.

Image queries and information aggregation: to boost speed and efficiency thanks to machine learning.
Techniques for detecting and observing changes: to reproduce a human interpretation, but with enhanced sensitivity via algorithms.

Contextualising and distributing high-added-value information

After processing, contextualisation of the data is essential in order to utilise the full potential of the satellite images. CVA propose GIS solutions that can be made available quickly and simply, and enable cross-processing with other information sources.

● Development and evolution of GIS (Geographic Information System)
● Installation and development of GIS infrastructure: web server, mapping server, distribution interfaces (the French government’s IGN Geoportal, Google Earth and Google Earth Engine, or a web portal solution devised in-house by CVA)
● Development of dedicated applications and tools for handling a wide range of data formats.

Plus points


Thanks to the large volume of images available free of charge, and in-house or open-source solutions, we offer cost-controlled solutions.


With our combination of discipline expertise and technical expertise – data, processing and IT – we are well placed to provide an optimum service.


Processing speed and efficiency are boosted by the addition of artificial intelligence.
