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.

Statistical analysis of drainage density from digital terrain data

Geomorphology, 2001
Drainage density (D-d), defined as the total length of channels per unit area, is a fundamental property of natural terrain that reflects local climate, relief, geology, and other factors. Accurate measurement of D-d is important for numerous geomorphic and hydrologic applications, yet it is a surprisingly difficult quantity to measure, particularly ...
