Every mapped stream and river in Australia! Map created with QGIS using data for 1.3 million streams from Geoscience Australia GEODATA TOPO 250K vector datasets. Many arid-zone rivers and streams in these maps are highly ephemeral, and may only flow once every few years or even decades. Streams are weighted by both ephemerality (perennial or non-perennial) and hierarchy (minor or major), with the highest weighting for major perennial rivers (i.e. Murray River).
Digital prints: High resolution digital prints of these maps (in lossless PNG file format suitable for printing on large canvases etc) are now available for purchase from my Etsy store!
