Sabah Biodiversity Experiment LiDAR Canopy and Terrain Models

1-meter resolution raster layers represent the canopy height model and digital terrain model for the Sabah Biodiversity Experiment in Malaysia. The Environmental Information Data Centre created these models from airborne LiDAR point cloud data collected in 2020. Data were collected to assess the effectiveness of restoration interventions for logged tropical forests.

Use Cases

• Analyze canopy height model (CHM) to quantify forest recovery rates across different restoration plots.
• Use digital terrain model (DTM) to model water flow and soil erosion potential in the experimental area.
• Compare CHM and DTM layers to study relationships between terrain features and canopy structure.
• Assess the impact of specific restoration interventions by analyzing spatial patterns in the 1-meter resolution CHM data.

Strengths

• 1-meter spatial resolution for detailed analysis
• Covers the entire Sabah Biodiversity Experiment site
• Includes both canopy height and digital terrain models derived from the same LiDAR survey

Limitations

• Single temporal snapshot from 2020, limiting change-over-time analysis
• Specific geographic focus on one experiment in Sabah, Malaysia, reducing generalizability
• Unknown total file size and raster dimensions
