Block 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 کاملIntegration of Lidar and Landsat Etm+ Data
Lidar data provide accurate measurements of forest canopy structure in the vertical plane however current lidar sensors have limited coverage in the horizontal plane. Landsat data provide extensive coverage of generalized forest structural classes in the horizontal plane but are relatively insensitive to variation in forest canopy height. It would therefore be desirable to integrate lidar and L...
متن کاملInterpretation of Tropical Vegetation Using Landsat Etm+ Imagery
Monitoring of tropical forest is important as it plays a vital role in Global biodiversity and terrestrial carbon dynamics. Remote sensing can be effectively used to monitor the tropical vegetation. However, an operational tool for interpretation and monitoring of tropical forest has not yet well developed. Therefore, the current study aimed to generate an interpretation key and a spectral libr...
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 کاملComparing 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...
