Comparing Aster and Landsat 7 Etm+ for Change Detection
The limited radiometric resolution and expiring life expectancy of the Landsat sensors have prompted this study to investigate the potential of using ASTER imagery in conjunction with Landsat imagery. This project developed methods to calibrate processed ASTER imagery and Landsat 7 ETM+ imagery to equivalent measurements for change detection studies. Landsat 7 ETM+ and ASTER imagery of southwes...
متن کاملAnalysis of Object-oriented Classification Results Derived from Pan-sharpened Landsat 7 Etm+ and Aster Images
In this study, performance of object-oriented classification approach has been tested using medium resolution satellite dataset of Zonguldak testfield. For this purpose, Landsat 7 ETM+ and ASTER images were used because of their nearly similar ground sampling distance (GSD). As a first step, pan-sharpened images were created based on the combination of panchromatic and color bands available in ...
متن کاملBlock Adjustement of Landsat-7 Etm Images
This research study shows the potential of large image-block adjustment with nadir viewing sensor images. The method uses the geometric correction system developed for multi-source images at the Canada Centre for Remote Sensing. The results with 15 Landsat-7 ETM images show that the same accuracy can be obtained with a large image block than with a single image using the same number of ground c...
متن کاملSurvey on Gap Filling Algorithms in Landsat 7 Etm+ Images
In remote sensing images the gapping is a known phenomenon. There are several reasons for image gaps, e.g. shadowed area for SAR data sets, cloud coverage for optical imagery and instrument errors such as SLC-off failure. On May 13, 2003 the Scan Line Corrector (SLC) of Landsat 7 Enhanced Thematic Mapper Plus (ETM+) sensor failed permanently causing around 20% of pixels per scene not scanned wh...
متن کاملLandsat-7 ETM+ Radiometric Stability and Absolute Calibration
Launched in April 1999, the Landsat-7 ETM+ instrument is in its fourth year of operation. The quality of the acquired calibrated imagery continues to be high, especially with respect to its three most important radiometric performance parameters: reflective band instrument stability to better than ±1%, reflective band absolute calibration to better than ±5%, and thermal band absolute calibratio...
