Measure NDVIs and Reflectances of custom areas
A custom region drawn in the Image Window may be used to measure the reflectance and NDVI of specific areas within a high resolution image. Transfer control to the Image Window, hold down the control key, then left-click and drag to draw a region.
If you are looking for a particular reflectance signature to measure, use the number keys 5-9 on the keyboard while active in the Image Window to view images in color (key 5), or in the 550nm channel (key 6), 650nm (key 7), 710nm (key 8), or 850nm (key 9).
Figures 1 through 5 below show the same custom region and its reflectance statistics, in the false color view, and each of the four bands.
