Surficial Geology Map of the Sand River Area

Alberta's Sand River area is mapped for surficial geology at a 1:250,000 scale. The data is a digitized version of AGS Map 178, originally created by Fenton and Andriashek and supplied by the Prairie Farm Rehabilitation Administration. It was last updated in March 2026.

Use Cases

• Classifying landform types using polygon features representing different geological units.
• Analyzing the spatial distribution of surficial materials like till or sand for resource assessment.
• Integrating geological polygon data with other GIS layers for environmental impact studies.
• Creating derivative maps for public education or regional planning based on the 1:250,000-scale mapping.

Strengths

• Digitized from an authoritative geological map (AGS Map 178) produced by subject matter experts.
• Data underwent quality checks and edits by the Alberta Geological Survey after receipt.

Limitations

• The specific number of polygon features, rows, and total dataset size are unknown.
• The original data collection date is not specified, potentially affecting temporal relevance.
• Limited to polygon features only; other map elements like lines or points may not be included.
