IMAGE

Within the CCSDS framework, the MHDC group has standardized a new hyperspectral image compression algorithm (CCSDS 123.0-B-2) and updated the CCSDS 121 compression algorithm (latest version named CCSDS 121.0-B-3).

MACCS is a cloud detection and atmospheric correction chain, adapted to the processing of high resolution image time series acquired under constant or quasi-constant viewing angles. In particular, it is used to process data from LANDSAT and SENTINEL-2.

MAJA

Open source

The MAJA (MACCS ATCOR Joint Algorithm, pronounced "maya") chain is a cloud detection and atmospheric correction chain.

WASP (for Weighted Average Synthesis Processor) is a processing chain to synthesize multiple Level-2A optical images from Maja into one single cloud-free image. It allows therefore to create periodically cloud-free synthesis images while keeping the seasonality (for classification for example).

The licensed software allows the detection of vehicles such as mobile homes, caravans, motor homes from an Earth observation satellite image (Pleiades type).

The licensed software allows the detection of "hard" constructions (houses) from an Earth observation satellite image (Pleiades type) or from an aerial image (BDOrtho type).
