Flow Routing Data for the Amazon and Yukon River Basins Using ISEA3H DGGS

ISEA3H DGGS-based flow routing datasets model water movement across two major river basins. The data was created by Chang Liao at the Pacific Northwest National Laboratory. It is available through the Papers with Code platform under an Open Access license.

Use Cases

• Modeling hydrological connectivity based on the Discrete Global Grid System framework.
• Analyzing watershed characteristics and flow accumulation in the Amazon and Yukon basins.
• Developing and validating terrain processing algorithms using the ISEA3H projection.

Strengths

• Focuses on two major, geographically distinct river basins (Amazon and Yukon).
• Built on the ISEA3H Discrete Global Grid System, a standardized geospatial framework.
• Authored by a researcher at a national laboratory (Pacific Northwest National Laboratory).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
