The Potential Impact of Vertical Sampling Uncertainty on ICESat-2/ATLAS Terrain and Canopy Height Retrievals for Multiple Ecosystems
With a planned launch no later than September 2018, the Ice, Cloud and land Elevation Satellite-2 (ICESat-2) will provide a global distribution of geodetic elevation measurements for both the terrain surface and relative canopy heights. The Advanced Topographic Laser Altimeter System (ATLAS) instrument on-board ICESat-2 is a LiDAR system sensitive to the photon level. The photon-counting techno...
متن کاملEstimates of forest canopy height and aboveground biomass using ICESat
[1] Exchange of carbon between forests and the atmosphere is a vital component of the global carbon cycle. Satellite laser altimetry has a unique capability for estimating forest canopy height, which has a direct and increasingly well understood relationship to aboveground carbon storage. While the Geoscience Laser Altimeter System (GLAS) onboard the Ice, Cloud and land Elevation Satellite (ICE...
متن کاملPost-Fire Canopy Height Recovery in Canada's Boreal Forests Using Airborne Laser Scanner (ALS)
Canopy height data collected with an airborne laser scanner (ALS) flown across unmanaged parts of Canada’s boreal forest in the summer of 2010 were used—as stand-alone data—to derive a least-squares polynomial (LSPOL) between presumed post-fire recovered canopy heights and duration (in years) since fire (YSF). Flight lines of the >25,000-km ALS survey intersected 163 historic fires with a known...
متن کاملCharacterizing woodland caribou habitat in sub-boreal and boreal forests
Woodland caribou (Rangifer tarandus caribou) are sensitive to changes in understory vegetation resulting from forest harvesting and are, therefore, of special concern for foresters and habitat biologists. Effective management of this species requires reliable habitat inventories which, because of the large heterogeneous areas over which caribou range, can be costly. We used Landsat Thematic Map...
متن کاملA Comparison of Forest Biophysical Parameters Assessed with Lidar Data on Three Platforms: Ground, Airborne, and Satellite
7 Lidar remote sensing from three platforms – ground, airborne, and spaceborne – has 8 the capability to acquire direct three-dimensional measurements of the forest canopy that 9 are useful for estimating a variety of forest inventory parameters, including tree height, 10 volume, and biomass, and also for deriving useful information for characterizing wildlife 11 habitat or forest fuels. 12 The...
