Abstract :
Compression technology is becoming increasingly important in geospatial information systems. In this paper we address some of the most relevant compression issues for remote sensing applications, and highlight the potential benefits of the JPEG set of standards. In particular, we review the JPEG, JPEG 2000, and JPEG-LS compression standards, and the JPIP protocol for interactive image retrieval. Finally, we discuss the use of compressed-domain processing, along with the use of flexible file formats for efficient storage and access to metadata.
