draw_elev2D_OCN

Function that plots the 2D elevation map generated by an OCN.

Generate and analyze Optimal Channel Networks (OCNs):
oriented spanning trees reproducing all scaling features characteristic
of real, natural river networks. As such, they can be used in a variety
of numerical experiments in the fields of hydrology, ecology and
epidemiology. See Carraro et al. (2020) <doi:10.1002/ece3.6479>
for a presentation of the package; Rinaldo et al. (2014)
<doi:10.1073/pnas.1322700111> for a theoretical overview on the OCN
concept; Furrer and Sain (2010) <doi:10.18637/jss.v036.i10> for the
construct used.
