The NASA VEGetation Workbench (VEG) is a knowledge based system that infers vegetation characteristics from reflectance data. The VEG Subgoals have been reorganized into categories. A new subgoal category 'Atmospheric Techniques' containing two new subgoals has been implemented. The subgoal Atmospheric Passes allows the scientist to take reflectance data measured at ground level .

Jefferson Davis Hwy., Suite . An expert system shell for inferring vegetation characteristics. By P. Ann Harrison and Patrick R. Harrison. Abstract. The NASA VEGetation Workbench (VEG) is a knowledge based system that infers vegetation characteristics from reflectance data. The report describes the extensions that have been made to the first generation version of : P. Ann Harrison and Patrick R. Harrison. All the NASA VEGetation Workbench (VEG) goals except the Learning System provide the scientist with several different techniques. When VEG is run, rules assist the scientist in selecting the best of the available techniques to apply to the sample of cover type data being studied. The techniques are stored in the VEG knowledge : P. Ann Harrison.

It has been integrated with the VEG system and requires that the VEG system be loaded to operate. VEG is the NASA VEGetation workbench - an expert system for inferring vegetation characteristics from reflectance data. The learning system provides three basic options. Using option one, the system learns class descriptions of one or more : Patrick R. Harrison and P. Ann Harrison. An expert system shell for inferring vegetation characteristics: Changes to the historical cover type database (Task F). The NASA Vegetation Workbench (VEG) is a knowledge based system that infers vegetation characteristics from reflectance data. A prototype of the VEG subgoal has been completed and the Help System has been added to the VEG system. It is loaded when the user first clicks on the option in the Tool Box Menu.
