Learning Objectives:
Formalize attribute values and domains in terms of set theory
Develop alternative forms of representations for situations in which attributes do not adequately capture meaning
Define Stevens’ four levels of measurement (i.e., nominal, ordinal, interval, ratio)
Describe particular geographic phenomena in terms of attributes
Determine the proper uses of attributes based on their domains
Characterize the domains of attributes in a GIS, including continuous and discrete, qualitative and quantitative, absolute and relative
Recognize situations and phenomena in the landscape which cannot be adequately represented by formal attributes, such as aesthetics
Compare and contrast the theory that properties are fundamental (and objects are human simplifications of patterns thereof) with the theory that objects are fundamental (and properties are attributes thereof)
Recognize attribute domains that do not fit well into Stevens’ four levels of measurement such as cycles, indexes, and hierarchies
