Topographic Maps of 23 Northern Quebec Villages at 1:2,000 Scale

Northern Quebec provides topographic maps for 23 Aboriginal villages at a 1:2,000 scale. The data was produced via photogrammetry from aerial photographs taken between 2009 and 2011, with planimetric accuracy of ±40 centimeters. It includes hydrography, communication routes, buildings, vegetation, geomorphology, and 2-meter equidistant level curves.

Use Cases

• Analyze building and structure density across 23 villages using the 'Buildings and various structures' feature for settlement pattern studies.
• Model flood risk by integrating hydrography features like bodies of water and watercourses with 2-meter equidistant level curves.
• Assess transportation network connectivity by mapping communication routes and road/airport infrastructures between villages.
• Classify land cover using combined vegetation and geomorphology features for environmental monitoring.

Strengths

• High planimetric accuracy of ±40 centimeters for spatial features.
• Covers 23 distinct villages across northern Quebec.
• Includes seven defined topographic components such as hydrography and level curves.

Limitations

• Data is temporally stale, derived from aerial imagery captured between 2009 and 2011.
• Precision may vary locally, as noted in the source description.
• No row or column count is provided, indicating unknown data volume and structure.
