Using JPEG data compression for remote moving window display
CCRS operates two remote sensing data satellite receiving ground stations (one in Prince Albert, Saskatchewan and the other in Cantley, Quebec), capable of receiving RADARSAT data, which are geographically distant from the RADARSAT mission control and data processing centres. In order to provide sensor data quickly and downlink quality assessment to the mission control centre and for other time-critical monitoring applications (quality assurance, ice monitoring, etc.), CCRS has developed two FastScan systems with industry. Each Fastscan is capable of processing the RADARSAT downlinked data into imagery and generates a moving window display (MWD) in real-time. The MWD imagery is also JPEG compressed into digital browse imagery which is suitable for electronic transmission to a remote site immediately following downlink reception. At the remote site, these JPEG files will then be re-assembled back and displayed on a MWD station as a complete swath, simulating a near real-time reduced resolution MWD. This paper describes the hardware and software development of the remote MWD station and its data communication link to the two satellite ground stations.
期刊介绍：
Remote Sensing Information is a bimonthly academic journal supervised by the Ministry of Natural Resources of the People's Republic of China and sponsored by China Academy of Surveying and Mapping Science. Since its inception in 1986, it has been one of the authoritative journals in the field of remote sensing in China.In 2014, it was recognised as one of the first batch of national academic journals, and was awarded the honours of Core Journals of China Science Citation Database, Chinese Core Journals, and Core Journals of Science and Technology of China. The journal won the Excellence Award (First Prize) of the National Excellent Surveying, Mapping and Geographic Information Journal Award in 2011 and 2017 respectively.
Remote Sensing Information is dedicated to reporting the cutting-edge theoretical and applied results of remote sensing science and technology, promoting academic exchanges at home and abroad, and promoting the application of remote sensing science and technology and industrial development. The journal adheres to the principles of openness, fairness and professionalism, abides by the anonymous review system of peer experts, and has good social credibility. The main columns include Review, Theoretical Research, Innovative Applications, Special Reports, International News, Famous Experts' Forum, Geographic National Condition Monitoring, etc., covering various fields such as surveying and mapping, forestry, agriculture, geology, meteorology, ocean, environment, national defence and so on.
Remote Sensing Information aims to provide a high-level academic exchange platform for experts and scholars in the field of remote sensing at home and abroad, to enhance academic influence, and to play a role in promoting and supporting the protection of natural resources, green technology innovation, and the construction of ecological civilisation.
