Vegetation Density Change Visualizations from Landsat Imagery

Landgate's Vegetation History product visualizes changes in vegetation density over three dates using a Landsat-derived vegetation index. It is designed for visual interpretation of trends, highlighting areas where vegetation density has increased or decreased.

Use Cases

• Visually interpret areas of vegetation density change over three dates using the derived vegetation index.
• Assess regional vegetation trends by comparing the visual displays of change over time.
• Identify potential areas of land cover change for further investigation with other data products.

Strengths

• Derived from Land Monitor's processed Landsat imagery, providing a standardized data source.
• Focuses on visual interpretation of change, offering a clear qualitative assessment of vegetation trends.
• Produced by Landgate, the authoritative Western Australian land information agency.

Limitations

• Data is intended for visual interpretation only and is not suitable for numerical summary or quantitative analysis.
• The specific vegetation index calculation (using red and short-wave infrared band 1) may limit direct comparison with other indices.
• Coverage is limited to the geographic and temporal scope of the underlying Land Monitor program.
