An Introduction and Problems of Compression Technology for the Particular Image : The Case of a High Resolution Earth Observation Satellite Data

Abstract

The earth observation satellite is utilized for monitor of the earth environments. It is In late years the quantity of data of satellite image increased by a high-resolution sensor. Therefore a satellite must transmit a large quantity of data Transmission ability of data is decided by a physical condition of a satellite. So compression of satellite data becomes necessary. ADEOS (Advanced Earth Observing Satellite) carries high-resolution optics sensor named "AVNIR". In this case "AVNIR" data is compressed by about 10% in order to reduce the transmission data rate. By this paper, I describe the reality of compression technology in satellite image and the problems that should be solved.
