John Harrington, Dept. of Geography, Kansas State University, Manhattan, KS 66506. Leavenworth, KS 66027-1399. KAP equipment has advantages of being easy to transport, simple to operate, and low in cost. We acquired KAP during the spring seasons of 1997 and 1998 over mature, hardwood forest at Fort Leavenworth, Kansas. KAP revealed the forest has a closed canopy, which is rough at the scale of individual trees.
Many shadows exist within the canopy.
The shadows are sub-pixel sized and are not visible on Landsat TM imagery, however. On this basis, KAP images suggest sub-pixel sized shadows from taller trees likely produce lower NDVI values derived from Landsat TM data. Continuing investigations are underway with stereo and multiband photographic techniques. Return to NASA EPSCoR at Emporia State University. Posted on 1 June 1999.
