On-orbit Spatial Resolution Estimation of Cbers-1 Ccd Imaging System from Bridge Images
The first China-Brazil Earth Resources Satellite (CBERS) was launched in 1999 and recently was substituted by CBERS-2. CBERS1 and CBERS-2 have the same specifications and carry three sensors which combine features that are specially designed to cover the broad range of space and time scales involved in the monitoring and preservation of the ecosystem: Wide Field Imager (WFI), High Resolution CC...
متن کاملPre-Launch Absolute Calibration of CCD/CBERS-2B Sensor
Pre-launch absolute calibration coefficients for the CCD/CBERS-2B sensor have been calculated from radiometric measurements performed in a satellite integration and test hall in the Chinese Academy of Space Technology (CAST) headquarters, located in Beijing, China. An illuminated integrating sphere was positioned in the test hall facilities to allow the CCD/CBERS-2B imagery of the entire sphere...
متن کاملIn-flight absolute calibration of the CCD/CBERS-2 sensor data
The success of any remote sensing program is directly related to the knowledge of both spectral and radiometric characteristics of the sensors involved. The Brazilian remote sensing user’s community has explored the relationship between orbital radiometric data and biophysical data since the beginning of the nineties using the Thematic Mapper (TM) sensor as the main source of data. Since the fi...
متن کاملIn-flight absolute calibration of the CBERS-2 CCD sensor data.
Since the first images of the sensors on board of CBERS-2 (China-Brazil Earth Resources Satellite) satellite were made available by the National Institute for Space Research (INPE), users have asked information about the conversion of image digital numbers to physical data (radiance or reflectance). This paper describes the main steps that were carried out to calculate the in-flight absolute ca...
متن کاملIdentifying Spatial Units of Human Occupation in the Brazilian Amazon Using Landsat and CBERS Multi-Resolution Imagery
Every spatial unit of human occupation is part of a network structuring an extensive process of urbanization in the Amazon territory. Multi-resolution remote sensing data were used to identify and map human presence and activities in the Sustainable Forest District of Cuiabá-Santarém highway (BR-163), west of Pará, Brazil. The limits of spatial units of human occupation were mapped based on dig...
