Kite aerial photography (KAP) is one kind of small-format aerial photography. KAP equipment
has advantages of being easy to transport, simple to operate, and low in cost. High-resolution,
low-height, airphotos may be taken frequently in order to document seasonal or ephemeral
conditions. We acquired KAP during the spring seasons of 1997 and 1998 over mature, hardwood
forest at Fort Leavenworth, Kansas. This forest is the subject of global-change research
involving Landsat TM imagery, tree-ring records, and weather data. 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.
