Drainage networks of Lancang-Mekong river basin (flow direction, flow accumulation, river networks)

1) Data content (including elements and significance)

This data set contains information of flow direction, accumulation of vector river network of Lancang Mekong River Basin.

2) Data sources and processing methods

In this data set, the remote sensing stream buring (RSSB) method (Wang et al., 2021) is adopted, and the high-precision elevation model MERIT-DEM and Sentinel-2 optical imagery are fused.

3) Data quality description

Validations show that this data set has high spatial accuracy (Wang et al, 2021).

4) Data application achievements and Prospects

This data set provides basic information of river networks, which can be used for hydrological model, land surface model, earth system model, as well as for mapping and spatial statistical analysis.

File naming and required software

This dataset includes two spatial units: basin, and sub-basin. Each spatial unit corresponds to a folder.

In each folder, there are files of flow direction (DIR), flow accumulation (ACC) and river networks (RIV).
