Andy Woodruff has invented a sort of hydrodynamics physics engine for interactive maps. It allows him to utilisation an animated map which visualizes H2O drainage period of time for whatever place on Earth.
In the Rain on the Terrain Andy tries to response the query of where H2O would period of time if you lot poured it over the terrain at whatever place on the planet. His solution is essentially to purpose tiptop information to honor the lowest following place for whatever given location. Drop closed to H2O at this place too it volition honor the path of to the lowest degree resistance too movement to the following place amongst this lowest elevation.
Repeat this procedure too you lot tin plot a long path of the to the lowest degree resistance, moving downhill. If you lot too thence animate a polyline along this path you lot tin utilisation a map of flowing rivers. Andy's map allows you lot to visualize the animated period of time map of drainage for whatever place on basis (based on his elementary algorithm). The map likewise includes closed to quick links to zoom the map to a publish of locations amongst interesting terrain.
