The Characterisation of Surfaces.

Extract from

Wood, J.D. (1996) The Geomorphological Characterisation of Digital Elevation Models, Ph.D. Thesis, University of Leicester, UK

Part One : The Parameterisation of Geomorphological Surfaces

Aims of parameterisation; Morphometric parameterisation - slope, aspect, surface curvature; Limitations of quadratic modelling; Importance of scale - multi-scale quadratic approximation, constrained approximation, weighted least squares; Spatial extensions - spatial autocorrelation lag diagrams, co-occurrence matrix lag diagrams.

Part Two : Morphometric Characterisation

Feature identification - quadratic approximation; Slope and curvature tolerances; Multi-scale feature classification; Hydrological modelling - drainage basin identification.

Part Three : Bibliography
