Terrain complexity and uncertainties in grid‐based digital terrain analysis

International Journal of Geographical Information Science, 2006
The objective of this research is to study the relationship between terrain complexity and terrain analysis results from grid‐based digital elevation models (DEMs). The impact of terrain complexity represented by terrain steepness and orientation on derived parameters such as slope and aspect has been analysed.

Geomorphology-oriented digital terrain analysis: Progress and perspectives

Journal of Chinese Geography, 2021
Digital terrain analysis (DTA) is one of the most important contents in the research of geographical information science (GIS). However, on the basis of the digital elevation model (DEM), many problems exist in the current research of DTA in geomorphological studies.

Semantic calibration of digital terrain analysis scale

Cartography and Geographic Information Science, 2014
Digital terrain analysis (DTA) provides efficient, repeatable, and quantified metrics of landscape characteristics that are important to the Earth sciences, particularly for detailed soil mapping applications. However, DTA has not been field tested to the extent that traditional field metrics of topography have been.

Multi-scale digital terrain analysis and feature selection for digital soil mapping

Geoderma, 2010
Abstract Terrain attributes are the most widely used predictors in digital soil mapping. Nevertheless, discussion of techniques for addressing scale issues and feature selection has been limited. Therefore, we provide a framework for incorporating multi-scale concepts into digital soil mapping and for evaluating these scale effects. Furthermore, soil

Digital Terrain Analysis Based on DEM

Frontiers of Forestry in China, 2006
The digital elevation model (DEM), an important source of information, is usually used to express a topographic surface in three dimensions and to imitate essential natural geography. DEM has been applied to physical geography, hydrology, ecology, and biology.
