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.

  • 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.
