Quebec Forest Stand Maps At 1:20,000 Scale

Forest maps from Quebec's second inventory cover the territory south of the 52nd parallel at a scale of 1/20,000. Each digital file, derived from scanned 125 cm x 75 cm paper cards, illustrates forest stands and covers approximately 250 km2. The data was prepared from photo-interpretation of 1:15,000 scale aerial photos.

Use Cases

• Classify forest stands by type of vegetation features like species, density, height, and stage of development.
• Map disturbances and defoliation class to assess forest health and pest impact across the region.
• Analyze the distribution of age class and slope classes for sustainable forestry planning.
• Integrate hydrography and transport network layers with forest stand outlines for multi-layer spatial analysis.

Strengths

• Covers almost all territory south of the 52nd parallel in Quebec, providing broad spatial coverage.
• High-resolution mapping at a scale of 1/20,000 with each file covering approximately 250 km2.
• Includes multiple thematic components such as forest stands, species, vegetation type, and topography.

Limitations

• Data is derived from scanned and interpreted paper maps, which may introduce digitization or interpretation errors.
• The description is an automated translation, which may obscure precise technical meanings of components.
• Specific quantitative metrics like row count, file size, or sample data are unavailable for assessment.
