Our business and know-how
TerraNIS is an innovative SME specializing in the design, development and sale of geoinformation services, derived from satellite/drone imagery, in the fields of agriculture, environment and land management. The company was founded in March 2014 by Marc Tondriaux and David Hello. Both have more than 25 years of experience in space applications, acquired in the Airbus group (first within Matra then Astrium / Infoterra / Spot Image).

Remote sensing
Our main raw material is the image, whether it comes from satellites or other sources as drones. Our core competence is our ability to choose the right image for the right use and to process it to extract accurate and relevant information. We use algorithms developed in-house or by our partners. For example, we use the Overland software developed by Airbus Defense and Space.

Proximity and partnerships
We are always looking to rely on local intermediaries to sell our services. Thanks to them, we are able to adapt our methods and our products to the local context (farming practices, regulatory framework etc). In the same way, we are always looking for the right partners, either commercial or technical, to expand our offer and improve our performance.

Business application
We always strive to be as close as possible to the needs of our end users. We therefore have people in our team who have a dual competence in remote sensing and agronomy or land use planning, capable of understanding our customers’ issues and of meeting their expectations as well as possible.

Genericity
We strive to develop high technology, high added value solutions that can be easily deployed in all territories. We can develop “custom” solutions but our credo is portability and genericity in order to offer services at the best price and with the best return on investment for our customers.
