TERAPIX (Traitement Élémentaire, Réduction et Analyse des PIXels) is an astronomical data reduction centre dedicated to the processing of very large data flows from digital sky surveys (like the CFHTLS, WIRDS or WUDS, NGVS, CFHQSIR, KIDS/VIKING, UltraVISTA) and giant panoramic visible and near infrared cameras (like MegaCam and WIRCam at CFHT, or OmegaCam on the VST and VIRCam on VISTA at ESO/Paranal).

TERAPIX is located at IAP (Institut d'Astrophysique de Paris). Its primary tasks are:
 to develop image processing and pipeline software for giant visible and near infrared cameras;
 to develop and provide tools for handling of large CCD visible and near infrared images;
 to operate pipelines and produce calibrated images and catalogues for wide field Legacy Surveys, Public Surveys, Large Programs or PI programs;
 to provide technical assistance and computing facilities for MegaCam and WIRCam users.
