Tundra Vegetation Elevation Models from LiDAR Scans in Barrow, Alaska

Six LiDAR scan positions captured a Digital Elevation Model of tundra vegetation at the NIMS site in Barrow, Alaska. The data was collected by the SCIOPS organization in late summer 2011. Results are provided as a series of xyz text files for each scan position.

Use Cases

• Generate high-resolution terrain models from the xyz point cloud data.
• Analyze tundra surface roughness and microtopography using elevation values.
• Study vegetation height and structure by comparing ground and surface returns in the LiDAR data.
• Create base maps for ecological research at the specific NIMS grid site.

Strengths

• Data captured from six distinct LiDAR positions for comprehensive site coverage.
• Focus on a specific, well-defined research grid (NIMS site) in Barrow.

Limitations

• Data is over a decade old, from a single campaign in 2011.
• Limited geographic scope to one specific grid in Barrow, Alaska.
• Unknown point density and accuracy metrics for the LiDAR scans.
