Learning Objectives:
Discuss the human predilection to conceptualize geographic phenomena in terms of discrete entities
Compare and contrast differing epistemological and metaphysical viewpoints on the “reality” of geographic entities
Identify the types of features that need to be modeled in a particular GIS application or procedure
Identify phenomena that are difficult or impossible to conceptualize in terms of entities
Describe the difficulties in modeling entities with ill-defined edges
Describe the difficulties inherent in extending the “tabletop” metaphor of objects to the geographic environment
Evaluate the effectiveness of GIS data models for representing the identity, existence, and lifespan of entities
Justify or refute the conception of fields (e.g., temperature, density) as spatially-intensive attributes of (sometimes amorphous and anonymous) entities
Model “gray area” phenomena, such as categorical coverages (a.k.a. discrete fields), in terms of objects
Evaluate the influence of scale on the conceptualization of entities
Describe the perceptual processes (e.g., edge detection) that aid cognitive objectification
Describe particular entities in terms of space, time, and properties
