چکیده
Remote sensing sensors are used in various applications from Earth sciences, archeology, intelligence, change detection or for planetary research and astronomy. Disaster management after floodings or earthquakes, detection of environmental pollutions or fire detection are examples of countless number of applications. The spatial as well as the spectral resolution of satellite image data increases steadily with new technologies and user requirements resulting in higher precision and new application scenarios. In the future, it will be possible to derive real-time application-specific information from the image on-board the satellite also based on high-resolution images. On the technical side, there is a tremendous increase in data rate that has to be handled by such systems. While the memory capacity requirements can still be fulfilled, the transmission capability becomes increasingly problematic.

متن کاملCompression of Multispectral Images On-board Observation Satellites
Compression reduces the amount of data to be sent to ground whilst preserving its content, allowing a lower bit-rate link to be used or more data to be sent over the same link. This paper presents the results of an investigation into image compression methods for multispectral images for use on-board small satellites. Suitable compression methods are described. An error resilience scheme is pro...
