IOTA² is a land-use map production line for large areas based on time series of Sentinel or Landsat images. In order to facilitate methodological contributions, IOTA² is open-source. As such, the channel makes extensive use of the image processing applications provided by Orfeo ToolBox.

Payload Data & Applications department for the maintenance and evolution of IOTA² to meet the needs of land use map production, as well as user support.


IOTA²’s main features are:

  • Automatic installation of the chain and its dependencies
  • Use of sensors of different types (optical/radar) to obtain better quality classifications. Understanding of different N2A product formats (THEIA + PEPS) to be able to classify as many geographical areas as possible.
  • Users can provide exogenous data as well as primitive data.
  • Possibility of spatially delineating learning zones.
  • Automatic calculation of primitives allowing the help to determine the label.
  • Merging classifications.
  • Automatic generation of coefficients allowing the evaluation of the quality of the classification.
  • Division into stages of the chain allows it to be launched only on very specific stages.
  • Combined use of Orfeo ToolBox multi-threading and MPI speeds up calculations.
