Historical Planimetric Maps of Alberta from 1949-1952

72 historical monochrome maps depict Alberta's landscape from aerial photographs taken between 1949 and 1952. The maps display the Alberta Township System, hydrographic features, highways, roads, pipelines, transmission lines, and municipalities. They are provided by the Government of Alberta in PDF, TIF, and geo-referenced PNG formats, but coverage for the province is incomplete.

Use Cases

• Analyze historical land development patterns based on the Alberta Township System grid
• Track changes in hydrographic features like rivers and lakes over time
• Study the evolution of provincial infrastructure such as highways, roads, pipelines, and transmission lines
• Compare historical municipal boundaries with contemporary maps

Strengths

• Maps are derived from aerial photographs taken during a specific period (1949-1952)
• Multiple file formats are available, including geo-referenced PNGs for most maps

Limitations

• Coverage for the province is incomplete and it is not known if further coverage will be added
• The maps are not available as GIS-ready data, requiring manual processing for analysis
• Row count and dataset size are unknown, which may limit suitability assessment
