Northeast Alaska Stream Networks Digitized From USGS Maps

Digital stream network data for Northeast Alaska, digitized from U.S. Geological Survey quadrangle maps. The data is organized by 7.5' or 15' quadrangles and was processed for geographic information systems use. The data was created by the organization CEOS_EXTRA.

Use Cases

• Mapping stream density and connectivity across 7.5' or 15' quadrangles for watershed analysis.
• Integrating digitized stream networks with other geospatial layers for habitat or infrastructure planning.
• Validating or updating modern hydrographic models with historically digitized USGS map data.

Strengths

• Data digitized from authoritative U.S. Geological Survey quadrangle maps.
• Digitized on a Talos table with a resolution of .001' for precise feature capture.

Limitations

• Unknown total spatial extent and number of stream features or quadrangles covered.
• Potential temporal staleness as the original USGS map publication dates are not provided.
