This document discusses land use in urban areas. It begins by asking questions about how land is used and what land uses can be identified from different data sources. It then presents several models of urban land use, including the Burgess, Hoyt, and MEDC models. Each model divides a city into concentric zones based on land use types such as residential, industrial, and commercial. The document discusses characteristics of different zones like the CBD, inner city, inner suburbs, and outer suburbs. It also contains questions to test the reader's understanding of urban land use patterns.
