Landscape Evolution: Tectonics,Climate and Topography“Evolution of Landscapes and What They CanReveal About Underlying ProcessesField of Geomorphology
PreviewTopography, Elevation and Relief of LandscapesDeciphering landscapes - the great geomorphicchallenge“Tectonics and Topography”Quantifying Landscapes’Closing the loop between internal and externalprocesses and understanding how they combineto create landscapes
Topography, Elevation and ReliefTopography:general shape of the surface of the EarthElevation:altitude of a point relative to sea levelContours:lines of equal value (e.g. topographic contours are lines of equalelevation)Relief:the difference between thehighest and lowest elevation in a particularareaToday, digital, griddedtopography data sets exist formuch of the world showingelevation intervals by colorDigital data sets are easilyanalyzed for relief, slope etc.
