In 1954 André Mémier created a chartered land surveying company and began developing photogrammetry services in 1961. Sintégra carried on this activity initially as an economic interest grouping (1971) and later as a company starting in 1987. Today, it is the oldest private French photogrammetry company. In 2006 our company was the first in France to offer airborne lidar services. At the same time, the company continued to expand its footprint in Grenoble and in the Auvergne-Rhone-Alpes region:


  • 2004 : it took over the chartered surveying company, CHALON (Voiron, Isère)
  • 2009 : it operated a merger with the CTGE chartered surveying company (Domène, Isère)
  • 2011 : it took over the chartered surveying company, MOURARET (St-Marcellin, Isère)
  • 2011 : it operated a merger with the engineering office, ARTIGEO (Vinay, Isère)


While continuing to develop our chartered land surveying expertise, our company and our chartered surveyors and topographers are innovating in the fields of topography and photogrammetry, while integrating new technologies such as:


  • Lidar
  • Mobile mapping
  • Bathymetry
  • Drone
  • 3D models
  • BIM…


Over the years, thanks to our multiple skills, we have provided support and advice to a wide range of clients including local authorities and land use planning stakeholders, individuals and promoters, engineering firms, architects, industrial and scientific sites, among others.
