GDW consensus global database
The GDW consensus global database
The GDW consensus global database (GDW-g) brings together the GDW core datasets shown below, with others, in a globally consistent way, enabling global-scale analyses. The consensus database is available for download here and for visualisation here. The associated paper is awaiting publication and will be linked here when published.
GDW Core datasets
Each of the three GDW core datasets has been developed over many years with a particular focus and methodology.
The Global Geo-referenced Database of Dams (GOODD) maps all dams visible on Google Earth satellite imagery globally; it catalogues the geospatial coordinates of 38,660 dams.
The Global Reservoir and Dam Database (GRanD) maps the location and attribute data of 7,320 dams greater than 15m in height or with a reservoir of more than 0.1km3.
Future Hydropower Reservoirs and Dams (FHReD) maps 3,700 dams that are under construction or in advanced planning stages. Together, these three datasets represent the most detailed, freely available global database of dams and georeferenced information about global dams.
Our consensus database brings these core datasets together, with others, in a globally consistent way, enabling global analyses.
