Vegetation Map of Auburn State Recreation Area from 2004

Spring 2004 vegetation map of the Auburn State Recreation Area in California, created by Tukman Geospatial LLC using 1-meter resolution IKONOS imagery. The map contains over 14,000 automatically generated polygon segments representing vegetation stands, with a minimum mapping unit of 1.5 acres.

Use Cases

• Train a segmentation model to identify vegetation stand boundaries from 1-meter resolution IKONOS imagery, using the over 14,000 polygon segments as ground truth.
• Analyze vegetation class distribution across the Auburn State Recreation Area using the polygon mapping units classified according to the Manual of California 1995.
• Validate automated image classification techniques for land cover mapping by comparing the project's combined automated and manual methodology results.
• Assess changes in vegetation cover over time by using the 2004 spring imagery and polygon stand boundaries as a historical baseline.

Strengths

• Contains over 14,000 detailed polygon segments representing vegetation stands.
• Based on high-resolution 1-meter spatial resolution pansharpened IKONOS imagery.
• Vegetation classification follows the standardized Manual of California 1995, translated to NVC Alliance concepts.

Limitations

• Temporal coverage is limited to a single snapshot from spring 2004, making it unsuitable for recent change analysis without newer data.
• The minimum mapping unit of 1.5 acres may not capture smaller or more fragmented vegetation patches.
• Data collection methodology relies on 2004-era image processing and classification techniques, which may be less advanced than current methods.
