Land Use Classification - an overview | ScienceDirect Topics

Land-use classification is intended to include both the intent and the reality of how a given land area within a metropolitan area may be altered by habitation and human use. Land-use categories, however, vary widely among communities and most have different taxonomies (e.g., ontologies).
