Title Proper : THE EFFECT OF FOREST CANOPIES AND VIEW ANGLES ON BINARY MAPPING OF SNOW COVER
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : Snow is an important component of the Earth's hydrologic and energy budgets andsignificant gains have been made in mapping snow properties using remote sensing. How-ever, the presence of forests complicates mapping and monitoring of snow from space.The fraction of the snow under forest canopies that is visible from above, or the viewablegap fraction (VGF), limits the information content of satellite data with respect to snow.The VGF is dependent on viewing geometry, canopy structure and surface topography.Results from both hemispheric photos and a geometric optical (GO) model quantify de-creases in VGF as the view zenith angle increases. Application of a GO model over alandscape shows that there is a substantial VGF decrease.-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
