process4EO enables the processing of satellite raw data to produce image products

process4EO is Deimos self-developed data processing module, currently in operations in the mission Deimos-2 as part of the gs4EO suite. It enables the processing of the satellite payload raw data to produce image products by performing the following operations on the input data:

  • Radiometric calibration, to convert the pixel elements from instrument digital counts into radiance units
  • Geometric correction, to eliminate distortions due to misalignments of the sensors in the focal plane geometry
  • Automatic geolocation, to compute the geodetic coordinates of the input pixels
  • Automatic ortho-rectification, to produce ortho-photos with vertical projection, free of distortions

These steps also generate quality-related figures of merit that are made available in all the products. Moreover, the product processors generate metadata, in line with industry standards, to facilitate the cataloguing, filtering and browsing of the product image collection.

In addition to the fully automatic processing chain, an advanced Manual Processing Chain User Interface is available, with the following main capabilities:

  • Product Viewer
  • Image Filtering Tools
  • GCP Tool
