Is there any tool to derive hypsometric curves from DEM/TIN ?

What software do you have at hand?

Did a little research, found a forum thread here which seems to indicate that ArcGIS spatial analyst extension can do what you require... which is to be expected, really, as that is what it's for.

It really depends (as frax indicated) on whether or not you have access to this software... at the very least, the capability to do this is out there, and knockoff GIS software may be able to perform the same task.

I have ArcGIS 9.2, QGIS, GRASS, GAT, TAS
there is an option in TAS but too complicated
