From 1985 till 1989, Y. Baudot worked as researcher at the University of Liège (Laboratory SURFACES), on contract for the Belgian National Research program in Satellite Remote Sensing (TELSAT program). He learnt there most of the techniques of processing and analysis of satellite images. The main domains of application were town planning and regional development.

From 1989 till 1994, he joined the team of the Laboratory of Remote Sensing and Regional Analysis of the Catholic University of Louvain-La-Neuve where he pursued his research in remote sensing but by centring henceforth his activities on the study of African cities (Morocco, Burkina Faso, Zaire).

These researches were rewarded by a PhD in Sciences, concretized by his thesis (1994) " Aerospatial Remote Sensing and Geographic Analysis of the Urban Population in Developing Countries ". For this study, an original method of classification of the remote sensing images was developed, and the statistical methods of sampling were adapted to the characteristics of the satellite data. Concrete examples allowed to produce maps of population of the cities of Marrakech and Ouagadougou.

These techniques were applied shortly afterwards, notably in a study of environmental impact of the industrial site of Mohammédia (Morocco), for the benefit of Tractebel-Environnement.

The expertise acquired in satellite remote sensing allowed to fine-tune software modules adapted to the needs of the urban economic planning in developing countries (pilot-study TELSAT / EUROSENSE).

An overview of the methods and techniques for data acquisition and image processing in remote sensing were presented to the general public in 2000 by Y. Baudot in a multimedia CD-ROM published by the program TELSAT (CD-ROM BEO-Belgian Earth Observation). This CD is now also available on Internet:

Y. Baudot also contributed to the diffusion of the knowledge about remote sensing by developing a presentation software based on Landsat data. This software was displayed during several years in the permanent exhibition(exposure) of the Space Centre of Redu ( Belgium).

In 2006, N.A.D.A.R. was part of a consortium in a resarch done for the European Space Agency about thje utilisation of satellite remote sensing to assess the environmental impact of hydro-electrical plants in Brazil:

In 2011-2014, Y. Baudot was at the origin of an ambitious research&development project called EO4REDD. This project aimed at developing a robust solution to quantify and certify the biomass of dense rain forest and to assess its evolution (deforestation and forest degradation). The proposed solution was based on using various type of earth observation satellites and low altitude stereoscopic aerial photos. The project was stopped in 2014 for stupid administrative reasons.
