Winnipeg Orthographic Aerial Photography Tiles

Orthographic aerial photography tiles provide georeferenced imagery for the city of Winnipeg. The dataset includes links to image files with associated metadata such as Year, Season, Resolution, and Location. It is published by data.winnipeg.ca and was last updated in October 2025.

Use Cases

• Create a geospatial index for image tiles using the Location and Year columns to analyze urban development over time.
• Train semantic segmentation models on the Image File data using the Season and Resolution columns to control for environmental and quality variables.
• Perform large-scale orthomosaic generation by stitching tiles based on their World File and Location metadata.
• Conduct temporal analysis of land cover change by comparing Image File data across different Year values.

Strengths

• Imagery is georeferenced under the NAD 83 UTM Zone 14 coordinate system, enabling precise spatial analysis.
• Metadata includes multiple relevant dimensions such as Year, Season, Resolution, and File Size for data selection.

Limitations

• The total number of image tiles (rows) and the overall dataset size are unknown, making project planning difficult.
• Sample data is unavailable, preventing assessment of image quality, format consistency, or null value prevalence.
