Yukon aerial photograph center points were produced from digitized paper flightline index maps. The dataset covers the period from 1946 to 1950 and is distributed by the Government of Yukon via GeoYukon.

Use Cases

• Georeference historical aerial photo center points for change detection analysis in Yukon landscapes.
• Analyze flightline patterns and photo coverage density across the Yukon territory.
• Integrate photo location points with other historical spatial datasets for environmental research.

Strengths

• Data covers a specific 5-year historical period (1946-1950).
• Originates from the authoritative Government of Yukon and is distributed via the official GeoYukon platform.
• Derived from systematic digitization of original paper flightline index maps.

Limitations

• Specific data volume (row count) and attribute details (columns) are unknown.
• Data format is web-service based (HTML, ESRI REST), not a direct downloadable file for offline analysis.
• Relies on historical paper maps as a source, which may introduce digitization errors or omissions.
