Gis-Based Expert Systems Model For Predicting Habitat Suitability Of Blackside Dace, Benjamin L. Blandford, John Ripy, Ted H. Grossardt, Ryan Evans, Sara Hines

Kentucky Transportation Center Presentations

This study presents a GIS-based predictive habitat suitability model for the blackside dace, a federally-listed threatened species of the Upper Cumberland River basin in southeastern Kentucky. The model is a rules-based system which incorporates expert knowledge about habitat preferences for the species. The five habitat factors identified by experts and included in this model are stream gradient, canopy coverage, riparian vegetation type, riparian zone width, and stream order. Using GIS, the five habitat parameters were parameterized and combined across the entire stream network. Combinations were evaluated by blackside dace experts in terms of habitat suitability. The resulting model was tested …


A.M.I.S. And The Partitioning Of Preference, Ted H. Grossardt Jul 2003

A.M.I.S. And The Partitioning Of Preference, Ted H. Grossardt

Kentucky Transportation Center Presentations

This presentation reviews work by the researchers that combines group dialogic techniques with analytic hierarchy and GIS to bring the knowledge of large groups of people to bear on a highway routing problem. A significant question is how technical knowledge and local information can be combined, either dialogically or mathematically, to provide the most faithful and practical version of a collaborative preference surface, what we call the Analytic Minimum Impedance Surface, or AMIS. While all preferences can be summed directly for this purpose, it may be more accurate and effective to partition the preference contribution to the landscape by knowledge …
