PE&RS August 2005

Cover Image

Featured on the cover are color composite images of an experiment forest near Howland, Maine from Jet Propulsion Laboratory’s Airborne Multi- Angle Imaging Spectrometer (AirMISR) (top) and NASA Goddard’s Laser Vegetation Imaging Sensor (LVIS) (bottom). AirMISR is a four channel digital camera that flies on an ER-2 aircraft at 20 km altitude. AirMISR’s single camera is swiveled to successive look angles to complete a desired set of multi-angle images with 27.5m pixel resolution. The false color image used near-infrared, red, and green channels from the 45.6o forward looking camera displayed as red, green, and blue, respectively. LVIS is an airborne laser altimeter system that acquires closely spaced 20 m footprint waveform information. The heights of waveform energy deciles of 100%, 50% and 25% were displayed as red, green and blue, respectively. The area shown has mature forest stands, different aged clear cuts and other forest harvesting treatment. Dark green areas on the AirMISR image are mature conifer forest, red areas are deciduous forest or grassy areas, light green or blue areas are non vegetated areas. The LVIS image shows no or short vegetation as black, taller mature forest stands as white and intermediate tones indicate forest structure differences. On August 31, 2003, LVIS obtained data at the same region. Images were acquired in August 2003. For more information, contact Jon Ranson, NASA GSFC, +1 301-614-6650
