标准范围
ISO 19144-2:2012规定了以UML元模型表示的土地覆盖元语言(LCML),允许基于地貌方面描述不同的土地覆盖分类系统。ISO 19144-2:2012还规定了LCML扩展寄存器的详细结构,但未规定寄存器的维护。ISO 19144-2:2012承认存在许多土地覆盖分类系统。它为任何通用土地覆盖分类系统的数据比较和集成提供了通用的参考结构,但并不打算取代这些分类系统。
ISO 19144-2:2012 specifies a Land Cover Meta Language (LCML) expressed as a UML metamodel that allows different land cover classification systems to be described based on the physiognomic aspects. ISO 19144-2:2012 also specifies the detailed structure of a register for the extension of LCML but does not specify the maintenance of the register. ISO 19144-2:2012 recognizes that there exist a number of land cover classification systems. It provides a common reference structure for the comparison and integration of data for any generic land cover classification system, but does not intend to replace those classification systems.
