%description
Functions for generating tables required for drawing and calculating
hypsometric curves and hypsometric integrals. These functions accept as
input the DEM of the region of interest (your watershed) and a spatial
data frame file specifying delineation of sub-catchments within the
watershed. They then generate output in the form of PNG images and HTML
files contained in a folder named "HYPSO_OUTPUT" created in the current
directory. S. K. Sharma, S. Gajbhiye, et al. (2018)
