Vector dataset for river systems originating in Eurasia to the Arctic Ocean
Abstract Arctic rivers are part of the freshwater resources for the Arctic and are of great significance to research into changes in the Arctic Ocean. However, global river datasets do not describe rivers in Eurasia in sufficient detail. Based on a 30-m resolution land surface water dataset in 2010...
