Introducing ATCOR
ATCOR® can be used for a broad variety of supported satellite and airborne sensor systems to retrieve physical parameters of the earth’s surface, i.e. surface spectral reflectance, emissivity and temperature. It uses a physical inversion process to retrieve consistent quantitative information. The version ATCOR-S is used for satellite sensors and ATCOR-A for airborne systems. All ATCOR versions support multispectral, hyperspectral as well as thermal infrared remote sensing data. ATCOR includes models for reflectance retrieval in rugged terrain, under the precense of clouds in shaded areas and for oblique observation angles.
The ATCOR® software product is developed and maintained by ReSe Applications LLC while the ATCOR® brand is held by DLR (German Aerospace Agency).
Note: The product “ATCOR® Workflow for IMAGINE” is an integrated version of ReSe’s ATCOR-S and is distributed exclusively by GEOSYSTEMS GmbH.

About ATCOR®
During the last decades, space-and airborne sensors have been widely used in different fields such as agriculture, meteorology, Earth sciences, geology, or exploration. Image acquisition is possible for clear and cloudy conditions and in areas difficult to access. Data acquisitions, however, are almost always conducted under conditions which require to thoroughly account for sensor calibration, atmospheric and illumination effects prior to a meaningful retrieval of geo-physical parameters such as surface spectral reflectance*, emissivity and temperature. Our physical approach of atmospheric correction software provides a practical solution to this problem. It improves the analysis of series of images since ground brightness variations caused by varying illumination conditions and atmospheric influences can be compensated.
Advantages of ATCOR®
- Usable without expert knowledge about atmospheric compensation
- Reflectance retrieval consistent over time and solar position
- Enables meaningful time series analyses through coherent reflectance and temperature retrievals
- Allows quantitative index analysis using absolute reflectances
- Supports a wide range of different sensors:
- Spaceborne: Landsat, SPOT, ASTER, Worldview, Pleiades, Planet-Scope, EnMAP, EMIT, PRISMA, Gaofen, Ikonos, Quickbird, RapidEye, VENuS, Sentinel, and many more
- Airborne: AVIRIS, Itres CASI, Specim AISA, NEO Hyspex/Mjolnir, Headwall Hyperspec, Resonon Pika, HyMap, and many more
- Easy definition and addition of new sensors
How ATCOR® Compares
ATCOR® is optimized for satellites and higher flight altitudes (i.e. > 2 km above ground). For lower flight altitudes, like typical for drones, DROACOR® can be used.
In comparison to similar software tools (e.g. FLAASH) for atmospheric compensation ATCOR® offers:
- Terrain topographic and illumination correction
- Haze-, cirrus-, and shadow-removal
- Batch processing
- Spectral and radiometric calibration
- model based BRDF correction (BREFCOR)
