Using color component overlays for result visualization in a classification by sketch system

Abstract

Geographic Information Systems (GIS) are notoriously difficult for users unfamiliar with the field, both for query formulation and for interpretation of display and results. Gaia is a graphical classification system which reduces this difficulty by using a sketch-like classification-by-example input interface, a fuzzy match of the classification against the GIS database, and the use of hue and saturation overlays to present results. This work presents Gaia's interface and result visualization mechanism.
