Hungarian cartographer Robert Szucs has created graphic maps of watersheds across the world. Photo: Grasshopper Geography
The maps trace the route of tributaries into rivers, and rivers into the sea. Photo: Grasshopper Geography
For the hydrographic maps, he uses Strahler Stream Order Classification, which defines stream size based on hierarchy of tributaries. Photo: Grasshopper Geography
Watersheds or catchment areas are grouped together with color. Photo: Grasshopper Geography
To create the maps, Szucs used Geographic Information Systems or GIS technology. Photo: Grasshopper Geography
