Scale Effect in Indirect Measurement of Leaf Area Index PROJECT TITLE :Scale Effect in Indirect Measurement of Leaf Area IndexABSTRACT:Scale impact, which is caused by a mix of model nonlinearity and surface heterogeneity, has been of interest to the remote sensing community for decades. But, there's no current analysis of scale result in the bottom-based indirect measurement of leaf area index (LAI), where model nonlinearity and surface heterogeneity additionally exist. This paper examines the dimensions effect on the indirect measurement of LAI. We tend to engineered multiscale data sets primarily based on realistic scenes and field measurements. We then implemented 5 representative ways of indirect LAI measurement at scales (phase lengths) that vary from meters to hundreds of meters. The results show varying degrees of deviation and fluctuation that exist in all 5 strategies when the segment length is shorter than twenty m. The retrieved LAI from either Beer's law or the gap-size distribution methodology shows a decreasing trend with increasing segment lengths. The length at that the LAI values begin to stabilize is concerning a full amount of row in row crops and a hundred m in broadleaf or coniferous forests. The impacts of segment length on the finite-length averaging technique, the mixture of gap-size distribution and finite-length strategies, and the trail-length distribution technique are relatively little. These three strategies stabilize at the segment scale longer than twenty m in all scenes. We tend to additionally realize that computing the typical LAI of all of the short segment lengths, which is often done, is inferior to merging these short segments into a extended one and computing the LAI price of the merged one.
