Surface analysis

These methods permit the kinds of surface analysis that you might expect to find in GIS software.

calc_aspect_at_node	Get array of aspect of a surface.
calc_hillshade_at_node	Get array of hillshade.
calc_slope_at_node	Array of slopes at nodes, averaged over neighboring patches.
calculate_slope_aspect_at_nodes_burrough	Calculate topographic slope.

Hex

calc_aspect_at_node	Get array of aspect of a surface.
