Montreal Island Aerial Photographs from 1947 to 1949

Montreal Island is documented in 3,920 aerial photographs taken between 1947 and 1949. The collection captures the territory's state prior to major urban planning and shoreline development projects.

Use Cases

• Train an image segmentation model to identify land cover types from the 1940s aerial photographs.
• Analyze shoreline and landform changes by comparing these 1947-1949 photographs with later aerial view datasets.
• Georeference and mosaic the photographs to create a historical basemap of Montreal Island for urban studies.
• Use the photographs as ground truth for validating the 1949 General Land Use Plans of Montreal.

Strengths

• Contains 3,920 individual photographic records.
• Covers a defined three-year period (1947-1949) crucial for pre-development baselines.
• Is part of a temporal series with linked datasets from 1925-1935 and 1958-1975 for change analysis.

Limitations

• Specific metadata columns for each photograph (e.g., coordinates, flight path) are unknown.
• Image quality and consistency across 3,920 photographs may vary due to historical capture methods.
• The dataset description and metadata were machine-translated, which may introduce ambiguities.
