Abstract
/9iR1
The development ot an "image" processing system is presented as it
relates to a research program to devise techniques to survey agricultural
conditions trom aerospace p1attorms.
The motivation tor the research and
arguments tor selected techniques are discussed.
Finally, the current
.,
.
"image" handling methods are outlined, and a system is proposed which
logically extends present capabilities.

INTRODUCTION
NASA and the U. S. Department of Agriculture are currently co-
sponsoring research to develop techniques to survey agricultural conditions
from aerospace platforms.
This program under the Laboratory for
Agricultural Remote Sensing (LARS) is presently concentrating on the use
of multispectral scanner imagery for this purpose.
One of the goals of
the program is to develop a means for making timely and accurate crop
surveys (acreage planted, projected yield, etc.) using airborne or space-
borne equipment on a nation-wide basis.
Due to the quantity of data
necessary in systems of this type it becomes mandato
