Historical Planimetric Maps of Alberta from 1949-1952

Planimetric Series maps initiated in 1949 display Alberta Township System, hydrographic features, highways, roads, pipelines, transmission lines, and municipalities. The maps are derived from aerial photographs taken between 1949 and 1952 and are provided by the Government of Alberta. Coverage for the province is incomplete and it is not known if further coverage will be added.

Use Cases

• Analyze historical infrastructure development based on roads and highways data
• Study changes in hydrographic features over time
• Map historical land parcel systems using Alberta Township System (ATS) data
• Trace the development of energy networks based on pipeline and transmission line data

Strengths

• Maps derived from aerial photographs taken during a specific period (1949-1952)
• Displays multiple specific features: Alberta Township System, hydrographic features, highways, roads, pipelines, transmission lines, municipalities

Limitations

• Coverage for the province is incomplete
• Maps are not available as GIS-ready data; formats are PDF, TIF, and roughly georeferenced PNG
• Column-level documentation is absent; field semantics must be inferred after download
