Freestyle Downhill H2o Mapping

Andy Woodruff has invented a form of hydrodynamics physics engine for interactive maps. It allows him to utilization an animated map which visualizes H2O drainage menstruum for whatsoever place on Earth.

In the Rain on the Terrain Andy tries to response the interrogation of where H2O would menstruum if you lot poured it over the terrain at whatsoever place on the planet. His solution is essentially to role superlative information to detect the lowest side past times side place for whatsoever given location. Drop only about H2O at this place in addition to it volition detect the path of to the lowest degree resistance in addition to motion to the side past times side place alongside this lowest elevation.

Repeat this procedure in addition to you lot tin plot a long path of the to the lowest degree resistance, moving downhill. If you lot hence animate a polyline along this path you lot tin utilization a map of flowing rivers. Andy's map allows you lot to visualize the animated menstruum map of drainage for whatsoever place on globe (based on his uncomplicated algorithm). The map equally good includes only about quick links to zoom the map to a publish of locations alongside interesting terrain.
