Visioterra sàrl

Founded in May 2004, VisioTerra is oriented towards Science Consulting for Earth Observation. This includes not only expert support, training and communication for EO programs, technical studies, software development of applications using virtual globes, scientific documentation editing, quality control assessment and reporting, instruments and products verification/control, new products and instruments specification and prototyping, audits, but also production of cartographic products to be ingested by GIS.

The list hereinafter describes some of the projects carried out by VisioTerra:


  • Cryosat over Arctic – Study of the potential of satellite data to monitor the environment in very cold areas.
  • Radar / optic coupling – Development and validation of methods to retrieve the optical signature of hydrocarbons from slicks detected by radar.
  • Detection of offshore wind fields from radar images – Development and validation of methods to detect wind fields at the surface of the sea from radar images.
    Oil seeps detection – Development and validation of methods to detect offshore oil seeps from wide field radar images.
  • E.O. Portal – Edition of Intranet pages specialised in Earth Observation (EO) defining the missions, instruments, programmes, events, agenda, spatial agencies, organisations… together with associated courses.
  • Multitemporal study of flooded areas – Analysis of the yearly cycle within the period 2006-2009. Classification of marsh zones and detection of anomalies due to anthropic activities.
  • Coastal erosion of Mandji peninsula – Compilation and accurate geocoding of optic and radar data (satellite and aerial photographs) acquired along the last 35 years. Photo-interpretation of coastal lines and development of tools to quantify erosions / accretions.
  • Study of Google Earth – Study, training and demonstrations of Google Earth for the fulfillment of business requirements in the domains of oil exploration, environment management and infrastructures.

REMA / World Bank

  • REMA Biodiversity Information System (RBIS) – Rwanda Environment Management Authority (REMA) – Support for the management of the RBIS from the invitation to tender up to the software development, data organization and trainings.


  • Audit of the SIGNE GIS – Assessment of the functionalities, document, manpower and computer resources of the GIS for the management of the Essonne basin. Editing of recommendations for the system extension.


  • GOCE L1b Products User Handbook – Editing of a second version of the handbook describing the acquisition physics, the algorithms, and the products of the gravimeter and positioning instruments onboard GOCE.
  • MERIS Product Handbook – Enhancement and correction of the MERIS product handbook introducing FAQ, applications and level 3 descriptions.


  • SPOT Vegetation / Envisat MERIS – Complementarity and comparison – Analysis of radiometry and geometry performances of both instruments. Paper presented on 2nd SPOT Vegetation W orkshop (Antwerp, 12-14 March 2004).

ESA / Brockmann Consult

  • CAL/VAL Portal – Generic description of missions and instruments using the SensorML language to support Calibration / Validation activities performed by the CEOS group.

DGA / Générale d’Infographie

  • Georeferencing study – Inventory of technical solutions and research actors in the field of georeferencing.


  • MERIS Geometry handbook – This handbook details the viewing geometry and provides algorithms and programs to orthorectify MERIS images from elevation ancillary data or external DEM.
  • DEM Quality assessment – Elevations found in ACE (ERS-1/2 Altimetry Corrected Elevations) and in SRTM30 are compared and assessed using external elevation values. Visual inspections results are also reported within a technical note.

Technical facilities and scientific environment

VisioTerra is located at the high technology pole of Marne-La-Vallée, located around 15 minutes from Paris. The immediate environment includes the University Paris-Est Marne-La-Vallée, the school of Ponts-et- Chaussée, the national school of geographic sciences, ESIEE, the school Louis Lumière and many other establishments of training and research
VisioTerra uses its proper computing power and the TELIMAGO image processing software, which is continuously upgraded to better carry out studies and cartographic production.
