Abstract
Report Preface: This bulletin was originally prepared for the National Aeronautics and Space Administration as part of an overall study to appraise potential benefits from obtaining land-use and other agricultural data from earth-orbiting satellites. Its purpose here is to present an overview of the current use of airphotos in a sample of countries selected as being representative. An attempt was made to include countries at varying stages of development from every continent except Antarctica. Some omissions of important applications of airphotos undoubtedly occur since not all applications have been documented. Moreover, with increasing usage in the past few years, particularly in the less developed countries, the available information may not be up to date. Even so, the handbook presents a reasonably accurate picture of current uses of airphotos in agriculture both in the United States and abroad.
