A set of tools to create georeferenced hillshade relief
raster maps using ray-tracing and other advanced hill-shading
techniques. It includes a wrapper function to create a georeferenced,
ray-traced hillshade map from a digital elevation model, and other
functions that can be used in a rayshader pipeline.

High Mach Finds Routes for Supersonic Aircraft

For supersonic aircraft, flying subsonic over land,
High Mach finds the best route between airports. Allows for coastal buffer and
potentially closed regions. Uses minimal model of aircraft
performance: focus is on time saved versus subsonic flight, rather
than vertical flight profile. For modelling and forecasting, not for planning your
flight!
