Atmospheric Correction Software for Airborne and Satellite Imaging
ATCOR® is a software product developed and maintained by ReSe Applications LLC. It was originally created by R. Richter at the German Aerospace Agency DLR and is further maintained by ReSe.
Two versions are available:
ATCOR-3 for satellite sensors and
ATCOR-4 for airborne optical and thermal scanner data.

Features
ATCOR® can be used for various supported satellite and airborne sensor systems to retrieve physical parameters of the earth’s surface, i.e. surface spectral reflectance, emissivity and temperature. ATCOR-3 for satellite sensors and both, flat and rugged terrain, and ATCOR-4 for airborne systems. All ATCOR versions support multispectral, hyperspectral as well as thermal infrared remote sensing data.

Value added products, e.g. LAI, Albedo, or heat flux
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-NG, Itres CASI, Specim AISA, NEO Hyspex/Mjolnir, Headwall Hyperspec, Resonon Pika, HyMap, and many more
- Easy definition and addition of new sensors
Alternatives to ATCOR®
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)
