Land Use, Land Cover and Change Mapping Geog 115A

Land Use:The use to which land is put

Land Cover: Characterization of the biophysical materials found on the land

Land use/cover classification systems Anderson Hierarchical Urban, Ag.,Range, Forest, Water, Wetlands, Barren, Tundra, Ice/Snow American Planning Association: Land Based Classification Standard Many more: e.g.FAO Africover, NIIRS, IGBP, etc. Minimum mapping unit: can vary by class

What is land use/cover change? From/To classes

Land use change in action

Land use mapping

Land cover classification Using human interpretation Using training: supervised classification Using an algorithm: automated, unsupervised Crisp Fuzzy
