Certified in land survey & basic photogrammetry by the Brazilian Army Geographic Survey (SGE). I expanded my studies into Photogrammetric Engineering at the International Training Center (ITC) in the Netherlands. And at the University of Stuttgart - Germany, in Digital Photogrammetry. I was employed at the Brazilian Space Institute (INPE) as a member of the team which pioneered the use of LANDSAT images on environmental and cartographic projects. Succeeding, I was employed by the Cartographic Branch of the Brazilian Institute of Geography and Statistics (IBGE), as team leader of the division of Aerial-Triangulation. I came to Canada to join a photogrammetric mapping company. Joining later, another Canadian company developer of an outstanding digital photogrammetric mapping system. I was an international representative of the German company K2-Photogrammetry.
