description The strength of GIS is its geospatial data model, which is a better representation of the world than the tabular model it replaced. Representing a network of streams as a collection of lines, for example, lets us see how stream locations match land use and other spatial characteristics of a watershed. Nevertheless, simple connected lines still do not adequately represent the richness of a real stream network. Real streams become wide rivers, flow over dams, split into braided channels, or flow into lakes, and our models must account for these characteristics.
