Name signature RIV
Data format Vector (lines)
Projection Geographic (latitude/longitude) referenced to WGS84 datum
Resolutions 15 arc-second
Line attributes ID unique identifier
Up_cells max. flow accumulation (number of cells) of stream reach
The river network layers distributed with HydroSHEDS are directly derived from the
drainage direction layers. The flow accumulation layer is used for selection and attribution.
Only rivers with upstream drainage areas exceeding a certain threshold are selected: for the
15 arc-second resolution a threshold of 100 upstream cells has been used. The vectorized
river reaches are currently attributed with the maximum flow accumulation (in number of
cells) occurring within each river reach. More attributes will be added in future versions.
We kindly ask users to cite HydroSHEDS in any published material produced using this data.
