A GUIDE TO AREA SAMPLING FRAME CONSTRUCTION
UTILIZING SATELLITE IMAGERY
A paper submitted to the United Nations at the
request of the United Nations Outer Space Affairs
Division based on material used and experience
gained at the Second International Training Course
in Remote Sensing Applications for Agriculture:
Crop Statistics and Agricultural Census.
25 April - 13 May 1977)
Preparation of this report would not have been possible without
the assistance of Dr. H.G.S. Murthy, Expert on Space Applications,
United Nations, New York, and Dr. John A. Howard, Head, Remote Sensing
Unit, Food and Agriculture Organization, Rome, Italy.
go to Ms. Berna Spiers, Technical Officer, Remote Sensing Unit, Food
and Agriculture Organization, for helping teach the course for which
this was prepared.
