Resistance Surface Components for Coastal Marten Landscape Connectivity

The Department of the Interior packaged processed datasets used to develop a resistance surface for coastal marten connectivity modeling. The collection includes data layers for roads, forested and non-forested land cover, rivers, waterbodies, bays, estuaries, and serpentine soils. Data are packaged in a geodatabase and ArcGIS Pro Map Package format, last updated on March 4, 2026.

Use Cases

• Model landscape resistance for least-cost path analysis based on the roads and rivers layers.
• Assess habitat connectivity based on forested and non-forested land cover classifications.
• Identify potential habitat corridors based on land cover on serpentine soils.
• Analyze barriers to movement based on waterbodies and bays/estuaries layers.

Strengths

• Includes multiple processed data layers (roads, rivers, land cover, waterbodies) for integrated analysis.
• Data is packaged in two formats (geodatabase and ArcGIS Pro Map Package) for different user workflows.
• Last updated date is March 4, 2026, indicating recent maintenance.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred from embedded metadata or a full report.
• Row count and dataset size are unknown, which may limit suitability assessment.
