Alberta Topographic Map Series at 1:250,000 Scale

83I Tawatinaw is a series of 50 color topographic maps covering the province of Alberta, produced by the Government of Alberta. The maps are at a 1:250,000 scale and use the National Topographic System (NTS) for naming. They display features including the Alberta Township System, 50-meter interval contours, hydrography, municipalities, roads, railways, and geo-administrative areas.

Use Cases

• Perform land-use planning and analysis based on the Alberta Township System (ATS) and geo-administrative features.
• Model terrain and hydrology based on 50-meter contour intervals and major hydrographic features.
• Analyze transportation and infrastructure networks based on major roads and railways.
• Create regional reference maps for field work based on combined topographic and administrative data.

Strengths

• Covers the full provincial extent of Alberta with 50 individual maps.
• Standardized 1:250,000 scale and National Topographic System (NTS) identifiers.
• Includes multiple feature layers: ATS, contours, hydrography, roads, railways, 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 digital analysis.
