'''JPEG2000''' ist ein Standard zur [[Bildkompression|Bildkomprimierung]], der auf der diskreten [[Wavelet-Transformation]] (DWT) beruht. Wie das bekannte JPEG ist er von der [[Joint Photographic Experts Group]] herausgegeben. JPEG2000 beherrscht sowohl verlustfreie als auch verlustbehaftete [[Datenkompression|Komprimierung]]. Mit dem Standard lassen sich zur Zeit ([[2005]]) die besten Komprimierungsraten für verlustbehaftet zu speichernde, fotoähnliche Bilder erreichen. Das Format kann eine Reihe von [[Metadaten]] aufnehmen, die das Verwalten und Auffinden von Bildern im [[Internet]] erleichtern.

JPEG 2000 is a wavelet-based image compression standard (ISO specification (ISO/IEC 15444)). It was created by the Joint Photographic Experts Group committee with the intention of superseding their original discrete cosine transform-based JPEG standard. Common filename extensions include .jp2 and .j2c, while the MIME type is image/jp2.

Although the JPEG 2000 standard format does not include geocoding, it does allow for extra information to be inserted within the file. So GeoJPEG2000 or GeoJP2 is a JPEG2000-File enhanced with extra geocoding information
