Analysis of Topography

This online tool implements the method published in: S. Hergarten, T. Wagner & K. Stüwe (2010) Age and prematurity of the Alps derived from topography. Earth and Planetary Science Letters, 297: 453-460

It is mainly designed for internal use, and unfortunately there is no documentation available so far.

Region	Resolution	Data source
Eurasia	3 arc seconds	SRTM3

^*ASTER GDEM is a product of METI and NASA.

Consider only region above	m elevation around the highest peak or around lat = , lon =
Disregard uplifted nodes
Include catchments of all points
Consider only the main river
Consider large catchments, too
Consider non-nearest neighbors, too
Map resolution	points per 100 km
Elevation smoothing	pixels
Slope smoothing	pixels
Elevation window size	m
Area step size
Elevation range (topography map)	– m
Slope range (slope map)	–
