83K Iosegun Lake: Alberta Provincial Topographic Maps at 1:250,000 Scale

50 color maps at 1:250,000 scale cover the entire province of Alberta. Each map is named using the National Topographic System identifier and displays the Alberta Township System, 50-meter interval contours, hydrographic features, municipalities, roads, railways, and geo-administrative features like parks. The series is provided by the Government of Alberta and was last updated on 2026-04-17.

Use Cases

• Perform land-use analysis based on displayed geo-administrative features like parks and reserves.
• Create elevation models or terrain analysis based on contour lines at 50-meter intervals.
• Map transportation networks for planning based on major roads and railways.
• Analyze hydrological patterns based on major hydrographic features.
• Integrate cadastral data using the Alberta Township System (ATS) grid.

Strengths

• 50 individual maps provide coverage for the entire provincial extent of Alberta.
• Standardized 1:250,000 scale and National Topographic System naming ensure consistency.
• Includes multiple layers of geographic information 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.
• Data may reflect geographic bias inherent to the Government of Alberta's mapping priorities.
