Figure 6. Feature space image with red reflectances on the X-axis and NIR reflectances (n = 2,230) on the Y-axis showing portioning of the feature space. HLS pixel values (same two bands systematically sampled from the 28-Dec-15 mosaic with n = 34,977) shown in black. Training and validation dataset shown in different colors by land cover class: Nonforest is tan, natural forest dark green, and forest plantations light green. Note that the feature space is well partitioned, but this single date does not afford sufficient class separation.
