SPOT VEGETATION for characterizing boreal forest fires
The potential of the recent SPOT VEGETATION (VGT) sensor for characterizing boreal forest res was investigated. Its capability for hotspot detection and burned area mapping was assessed by analysing a series of VGT, NOAA/AVHRR, and Landsat TM images over a 1541 km2 re that occurred in May 1998, in Alberta, Canada. VGT’s 1.65mm, short-wave infrared (SWIR) channel was capable of detecting the...
متن کاملForest fire scar detection in the boreal forest with multitemporal SPOT-VEGETATION data
—Disturbance events, such as fire, have a major impact on boreal forest dynamics, succession and the global carbon cycle. Methods using satellite imagery are well established for detecting forest fires in real time and mapping the burned area (fire scars) within one year of the fire. This paper focuses on the detection of older fire disturbance-regeneration patterns in the boreal forests of Can...
متن کاملClassifying Compressed Lidar Waveform Data
Full waveform recording is becoming increasingly affordable and, consequently, available in today's state-of-the-art LiDAR systems. Therefore, there is no practical limitation to the complexity of pulse detection and other methods that can be applied in post-processing mode. Analyzing the entire return signal, the full waveform can provide additional geometrical and physical information about t...
متن کاملEstimating fire-related parameters in boreal forest using SPOT VEGETATION
The majority of burning in the boreal forest zone consists of stand replacement fires larger than 10 km occurring in remote, sparsely populated regions. Satellite remote sensing using coarse resolution (c 1 km) sensors is thus well suited in documenting the spatial and temporal distribution of fires in this zone. The purpose of this study was to investigate the utility of the SPOT VEGETATION (V...
متن کاملDelineation of Vegetation and Building Polygons from Full- Waveform Airborne Lidar Data Using Opals Software
Full-waveform LiDAR is an active remote sensing technique that provides the scattering properties of the targets i.e. amplitude and echo width (EW) in addition to 3D point clouds. The amplitude provides information on the target's reflectance and the EW is a measure for the range variation of scatterers within the laser footprint contributing to a single echo and is, therefore, an indicator for...
