Definition: Classification for Land Use Statistics: Eurostat Remote Sensing
Clusters nomenclature, version 1.1, is a pilot classification used under urban, regional and cross-border projects. Version 2.0 is experimental: it introduces descriptors' method. The CLUSTERS classification is designed to satisfy the requirements of a large circle of users. It is a fairly consistent "multi-user" statistical platform which includes the proven features of existing statistical classifications and takes account of the processing and construction constraints specific to land use statistics (spatial coherence, thematic coherence, consistency of scale, consistency over time, etc). Basic principles of the nomenclature: The main assignment principle is the rule of proportion. The rule of the dominant characteristic is used for artificial areas. The rules of assignment of mixed uses by juxtaposition are also defined. Principles of construction of the nomenclature: An approach on the basis of three groups of descriptors (functional, biophysics, and complementary) is in hand. These descriptors are applicable for assignment of objects within the nomenclature. Each category can then be characterized by a hierarchical sequence of these descriptors which can be applied systematically at the most aggregated level of the nomenclature and in a way more specific to more detailed levels. Descriptors of a functional nature were judged priority: they determine the classification of objects at the most aggregated level of the nomenclature in relation to the biophysical descriptors. Qualities of the classification: The nomenclature is exhaustive and checks the conditions of non-overlapping. Categories and aggregates are defined with precision and postpone limited cases to other categories or aggregates. The nomenclature proposes a standard system for studying the land use of European countries. Clusters answers to needs of a broad community of users. The hierarchical combination of various descriptors makes it possible to build the tree of the nomenclature. Clusters takes into account official classifications on land use at European level (Cronos, Farm Structure Surveys, Forest definitions of Eurostat, ECE nomenclature of the UN).
