Maps of which way Amazon rivers and land drain
What it measures. Detailed maps of how water drains across the Amazon River basin, showing stream networks, the direction land and rivers flow, tributary boundaries, and river mouths and sources, at roughly 500-m detail.
How it's made. Created with a topography-independent analysis method applied to an existing vector river network (the Digital Chart of the World), delivered as shapefiles and image files.
How & where you'd use it. Used to understand drainage and water flow across the Amazon basin, supporting hydrology and ecosystem studies of the region.

Official description
This data set provides high-resolution (~500 m) gridded land and stream drainage direction maps for the Amazon River basin, excluding the Rio Tocantins basin. These maps are the result of a new topography-independent analysis method (Mayorga et al., 2005) using the vector river network from the Digital Chart of the World (DCW, Danko, 1992) to create a high-resolution flow direction map. The data products include (1) a stream network coverage with stream order assigned to each reach; (2) the basin boundaries of the major tributaries to the Amazon mainstem; (3) the mouths; and (4) the source points of these tributaries. There are 7 ESRI ArcGIS shapefiles provided in compressed *.zip format and 4 GeoTiff image files with this data set.
