Defining a hierarchy of spatial entities for environmental analysis and modeling using digital elevation models (DEMs)
AbstractNumerous investigators have examined ways in which digital elevation data can be used to define landform-based units that act as basic spatial and structural entities for soil, terrain or ecological maps. No proposed system of automated terrain or ecological mapping has, to our knowledge, advanced beyond research investigation to achieve routine operational use. This paper describes a conceptual design for creating landform-based spatial entities from digital elevation data to support multi-level, hierarchical integrated natural resource inventory. The spatial entities defined by our procedures embrace both geomorphic and hydrological considerations. They are intended to provide a framework for mapping more specific ecological entities of interest.
