Abstract
The main objective of this study was to provide information useful in determining how, and to what extent, remote sensing might help in supplying more accurate, comprehensive, and timely data on crop areas, crop yields, crop production, and land use around the world. Remote sensing is the method used to collect such data about the earth's surface. This method utilized optical, electro-optical, and electronic devices mounted in airplanes or satellites. Remote sensing promises to close some of the remaining gaps in available data, and to improve data quality and timeliness. It may be possible, through remote sensing, to replace some present methods with less costly methods.
