7,005 square kilometers of lidar data covering fourteen partial counties in Utah, with partial coverage of three counties in the Minidoka National Wildlife Refuge. The data was acquired in fall 2016 by Quantum Spatial, Inc. for the Department of the Interior. It includes classified LAS files, digital elevation models, digital surface models, intensity imagery, and breaklines.
Use Cases
- Generate bare earth terrain models based on the classified LAS files and DEMs.
- Analyze surface features and first returns based on the digital surface models.
- Map hydrological features and breaklines based on the continuous breaklines in shapefile format.
- Create intensity maps for land cover analysis based on the tiled intensity imagery.
Strengths
- Data covers approximately 7,005 total square kilometers.
- Vertical accuracy was assessed using 28 ground control points and 11 independent checkpoints.
- Data was collected at a nominal pulse spacing of 0.35 meters.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
