Topography
==========

This section provides examples of how to use the :ref:`api-surface` and :ref:`api-morphology` components of Cratermaker to model the surface topography of craters and the topographic evolution of cratered surfaces.

This will mimic how CTEM generates a test crater, though it is much simpler to run than that venerable old Fortran-based beast of a code!. The crater is created with a radius of 1 km. The hill shade uses the same settings that CTEM uses.">
