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.
Adopting the best remote sensing approach will require problem definition and the responses to the following four questions;
1. What are the targets?
2. What level of interpretation is needed?
3. How can the targets be sensed?
4. What are the available resources and required data?
In addition to these questions and responses, the following 6 points should be considered;
1. The need for a human interpreter increases as the required level of interpretation increases.
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.
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.
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.
5. The costs for data and analysis should be justified and minimized.
6. Advanced technology should be integrated and amalgamated with conventional technology.
The influence of recent advances in computer technology and satellite sensors on approaches to problem solving is also discussed.
It is highly recommended that the points emphasized here should be considered and the best approach should be adopted in need of developing countries.
