Steps Toward Terrain Knowledge Acquisition

During this phase, progress was made towards identifying, representing, and formalizing, and implementing aspects of terrain related knowledge relevant to drainage courses (according to Dr.J. Rinker's Pl Guide) and the alluvial fan associated landforms including the representation of information related to physiographic information, e.g., Basin and Range. The relevant conceptual knowledge is being structured in the form of rules and objects. Opportunistic problem solving seems to fit this photointerpretation problem better that a forward or backward search of the state space. The appended objects and rules show examples related to knowledge representation of selected drainage courses (gorge, wash, ravine) as well as of alluvial fan morphology, physiography and regional context. There are are also examples of rule executions (firings) for wash and ravine
