...…technologies, such as hyperspectral sensors, have already been successfully applied to tree species–level classification at relatively fine scales (Clark et al. 2005), future studies may combine the capacities of MODIS (at 250–500-m resolution) with other high-resolution remote sensing to…...

...For LDA classification, the pooled within-class covariance matrix and predictor variables (e.g., reflectance values) from training samples are used to build classification equations, or discriminant functions for each class (Duda & Hart, 1973; Tabachnick & Fidell, 1989)....
