Community Landscape Hazard Map For Old Crow Yukon

A 30-meter resolution landscape hazard map for Old Crow, Yukon, identifies geological risks like landslides and permafrost instability. The map incorporates multiple data inputs including surficial geology, topography, and future climate projections to assess hazards under changing conditions. It was produced by the Northern Climate ExChange as part of a community hazards mapping program.

Use Cases

• Classify landscape hazard zones using stoplight color coding for community land-use planning.
• Analyze correlations between permafrost distribution data and identified permafrost stability hazards.
• Integrate surficial geology and topographic slope data to model potential landslide risk areas.
• Use future climate projections alongside past hydrological trends to assess flood hazard potential.

Strengths

• Hazard assessment incorporates multiple specific data inputs: surficial geology, topography, permafrost distribution, and climate projections.
• Map is presented in an intuitive stoplight color scheme designed for community decision-makers.
• Detailed methodology and data inputs are documented in an accompanying report available for download.

Limitations

• Data is specific to the Old Crow community area, limiting broader geographical applicability.
• The primary format is ESRI REST, requiring GIS software for full analysis and use.
• Sample data and specific row/column counts for underlying data are unavailable for review.
