abstraction


Quick Reference

The selection and conceptualization of a phenomenon, or some aspect of it; a way of viewing a real world object, usually a simplification—such as a model. Data abstraction captures the essential information needed to describe a spatial phenomenon and is fundamental in geographic information science.

See Smaalen in M. J. Kraak and M. Molenaar, eds (1996) for a hierarchical rule for geographic information abstraction.
