area of developed space with high usage intensity According to the NLCD 2011, areas of developed space under high intensity usage are dominated by constructed features where humans reside and work. Examples include apartment complexes, row houses and commercial/industrial facilities. Further, it is asserted that "impervious surfaces", most likely referring to concrete and related substances, cover between than 80 - 100% of the area. Such thresholds - which are themselves fuzzy - are not strictly asserted in this definition. NLCD:24 This class is in need of refinement, particularly in linking to other entities in the ontology. This would be helped by more clear listings of entities included in this classification. However, the class is suitable for use in annotating remotely sensed land types. nlcd2011 An area of developed space used for high intensity purposes such as accommodating dense and multi-occupant residential, commercial, and industrial units. This area is in contact with an atmospheric column extending from the planetary boundary layer to the planet's exosphere with little to no physical obstruction. developed, high intensity area of developed space
