And yet how inconceivably complicated are the contour-lines precisely along that line, as they are indeed for the matter of that in any of the other sand-free parts of the Lop Desert!

Hypsometric analysis (or area-altitude analysis) is the study of the distribution of horizontal cross-sectional area of a landmass with respect to elevation. Classically, hypsometric analysis has been used to differentiate between erosional landforms at different stages during their evolution.
