BOREAS RSS-08 SSA IFC-3 Digitized Stereo Imagery at the OBS, OA, and OJP Sites Summary The RSS08 team acquired stereo photography from the double-scaffold towers at the Southern Study Area (SSA) Old Black Spruce (OBS), Old Aspen (OA), and Old Jack Pine (OJP) sites during IFC-3 in 1994. The imagery of the canopy was taken from various perspectives. The RSS08 team also measured BRDF at the SSA-OA and -OBS sites during IFC-3.

When possible canopy stereo photographs were acquired with reference to a hand held calibration frame. Three main categories of imagery were acquired: 1. Tree canopy crowns (from the side and above the canopy) 2. Understory 3. 360 degree rotation coverage showing tree stem spacing at a height of almost 2m. The digitized stereo imagery is in TIFF format.

These data files contain information for the right and left photographs of 6 different film areas. These areas are: Film# Contents ----- --------- 1 Old Jack Pine tree canopy and ground . 2 Old Jack Pine 360 degree rotation coverage. 3 Old Jack Pine 360 degree rotation coverage contd, lichen, Old Aspen understory (hazelnut). 4 Old Aspen canopy and understory (hazelnut). 5 Old Black Spruce canopy, ground sideviews. 6 Old Black Spruce understory 360 degree rotation.

All the TIFF files were scanned at a resolution of 150 dpi and show all 12 frames exposed for each roll of film.
