Summary Landsat 5 was launched on March 1, 1984, carrying a seven-band TM sensor, and still operates properly at present. The satellite takes a sun-synchronized orbit with 705km altitude and 98.22 deg. inclination.
A TM scene covers 185km by 170km earth surface approximately, with 30m ground resolution for band 1,2,3,4,5,7 and 120m for band6. For a particular place, ... the revisit cycle of the satellite is 16 days.
Chaina Remote Sensing Satellite Ground Station(CRSGS) was inaugurated and become operational in Dec. 1986. Up to now it is the most important source of remote sensing satellite data in China for earth resouce exploration and environment monitoring.
CRSGS has provided a large amount of satellite remote sensing products to more than 400 users, domestic and abroad. Applications of TM images have resulted in great economic and social benefits in a wide range of areas of national economy: resource survey and utilization, environment monitoring, geographic cartography, minerarl exploration, disaster detecting and assessing, etc.
TM data received by CRSGS since 1986 have been archived. Through a Catalogue Archive and Browse System(CABS), users can retrieve useful information about data of interests. A image(or a group of images) could be searched according to date, location(latitude-longitude or path-row), and quality, etc. Text catalogue is available for all TM data in the archival. In addition to text contents, sub-sampled browse images are available for data acquired after Apr.,1994.
The major products of CRSGS are TM data on CCTs, floppy disks and imagery on films or papaer prints. Products fall into two categories with respect to processing methods. 1. Standard processing includes systematic correction, precision correction, and geocoding, etc. 2.Special product(user dependent) includes multi-scene mosaicking, image classification, user defined annotation or administrative boundary adding, special juts enhancement, etc. Geographic Coverage
