A framework of questions and significant points to be considered is outlined for those in developed countries who advise developing, countries on their problem solving with remote sensing.<BR>Adopting the best remote sensing approach will require problem definition and the responses to the following four questions;<BR>1. What are the targets?<BR>2. What level of interpretation is needed?<BR>3. How can the targets be sensed?<BR>4. What are the available resources and required data?<BR>In addition to these questions and responses, the following 6 points should be considered;<BR>1. The need for a human interpreter increases as the required level of interpretation increases.<BR>2. Spectral and computer approaches are valuable when seeking surface information, but they are often of little or no real value when. seeking subsurface information--the latter being more dependent on human interpretation.<BR>3. As the required spatial resolution and spectral sensitivity approach the limits of the sensor, the need for applying the original remotely sensed data increases.<BR>4. A remote sensing approach cannot produce results of some specified reliabilty and geometric accuracy unless all input data are of that reliability and accuracy.<BR>5. The costs for data and analysis should be justified and minimized.<BR>6. Advanced technology should be integrated and amalgamated with conventional technology.<BR>The influence of recent advances in computer technology and satellite sensors on approaches to problem solving is also discussed.<BR>It is highly recommended that the points emphasized here should be considered and the best approach should be adopted in need of developing countries.
