ATCOR Workflow for IMAGINE - Features

ATCOR Workflow for IMAGINE in IMAGINE Essentials

The architecture behind the ATCOR Workflow for IMAGINE is the Spatial Modeler framework within ERDAS IMAGINE. But no worries - you can, but you don‘t have to be familiar with the Spatial Modeler to benefit from ATCOR Workflow for IMAGINE.

ATCOR Workflow for IMAGINE comes with an easy-to-use dialogue in IMAGINE Essentials that leads you step-by-step through the dehaze and correction workflow. Main parameter settings are set by default, and the import of metadata and calibration file information run automatically.

ATCOR Workflow for IMAGINE in IMAGINE Professional

Advanced users will find it useful to work with ATCOR Workflow for IMAGINE within the Spatial Modeler in IMAGINE Professional. Here you have access to all ATCOR operators containing the functionality for dehazing and atmospheric as well as topographic (illumination) correction.

By integrating the ATCOR operators in your individual workflow, you are able to set up a Spatial Model for a complete image analysis chain. Thus, your data processing runs fully automatic from data import through dehazing and atmospheric correction, over to the image analysis (e.g. NDVI) into the final output of geoinformation products.


  • Features3 modules:
    • ATCOR-2 for flat terrain
    • ATCOR-3 for rugged terrain
    • Dehaze
  • Superior dehaze algorithm.
  • Retrieval of surface reflectance, emissivity and temperature by atmospheric and topographic correction.
  • Automatic metadata import.
  • Fully automatic algorithm for statistical haze and cirrus cloud removal.
  • Fully integrated DEM preparation.
  • BRDF correction in rugged terrain.
  • Calculation of value-added products, e.g. LAI, FPAR, Albedo.
  • Support of more than 30 commercial and noncommercial sensors, e.g. Sentinel-2, WorldView, SPOT, Pléiades, Landsat, PlanetScope.
  • The core functionality in the background is based on IDL (Interactive Data Language). The ATCOR Workflow for IMAGINE installer comes with the license-free IDL Virtual Machine. An extra commercial IDL license is not required, but is useful e.g. for unattended batch processing.
