Alberta Provincial Topographic Maps at 1:250,000 Scale

A series of 50 color topographic maps covering the entire province of Alberta at a 1:250,000 scale. The maps display the Alberta Township System, 50-meter interval contours, hydrographic features, municipalities, roads, railways, and geo-administrative features like parks and reserves. The data is provided by the Government of Alberta and was last updated in April 2026.

Use Cases

• Land parcel identification and analysis based on the Alberta Township System (ATS) grid.
• Terrain modeling and elevation analysis based on 50-meter interval contour lines.
• Infrastructure and transportation planning based on mapped roads and railways.
• Environmental and hydrological studies based on major hydrographic features.
• Recreation and protected area management based on geo-administrative features like parks and reserves.

Strengths

• Covers the full provincial extent of Alberta with 50 individual map sheets.
• Standardized at a consistent 1:250,000 scale using the National Topographic System (NTS).
• Includes multiple thematic layers such as contours, hydrography, and administrative boundaries.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale automated analysis.
• Data may reflect geographic bias inherent to the Government of Alberta as the sole source.
