Integration of Landsat TM and SPOT HRG Images for Vegetation Change Detection in the Brazilian Amazon.
Traditional change detection approaches have been proven to be difficult in detecting vegetation changes in the moist tropical regions with multitemporal images. This paper explores the integration of Landsat Thematic Mapper (TM) and SPOT High Resolution Geometric (HRG) instrument data for vegetation change detection in the Brazilian Amazon. A principal component analysis was used to integrate ...

متن کاملBurnt area mapping across Canada ' s boreal forest zone using SPOT VEGETATION calibrated with Landsat TM imageR ) fJ
Wildfires are a major source of disturbance to the boreal forest ecosystem as they have been documented to bum as much as 1.5 percent (22 million ha) of its global area in a single year (Cofer et a!., 1996). Fires in this ecosystem typically kill the standing trees and thus exert a dominant control on landscape level patterns of forest succession and stand age distribution (Johnson, 1992). Fire...
متن کاملRetrieval and Comparison of Forest Leaf Area Index Based on Remote Sensing Data from AVNIR-2, Landsat-5 TM, MODIS, and PALSAR Sensors
Remote sensing data from multi-source optical and SAR (Synthetic Aperture Radar) sensors have been widely utilized to detect forest dynamics under a variety of conditions. Due to different temporal coverage, spatial resolution, and spectral characteristics, these sensors usually perform differently from one another. To conduct statistical modeling accuracies evaluation and comparison among seve...
متن کاملMapping Vegetation and Forest Types using Landsat TM in the Western Ghat Region of Maharashtra, India
Vegetation plays a key role in reducing ambient temperature, moisture and pollutant capture, energy use and subsequent ground level ozone reduction. In recent years vegetation mapping has become increasingly important, especially with advancements in environmental economic valuation. The spatial information from the remote sensing satellites enables researchers to quantify and qualify the amoun...
