Devils River Lidar, Sonar, and Orthophoto Data from Juno to Lake Amistad

The Devils River in Texas, from Juno to Lake Amistad, is the focus of this dataset. It includes topographic and bathymetric lidar, orthophotos, sonar, and ground-penetrating radar data, with detailed coverage of a two-kilometer pool. John Andrews contributed this data to the Texas Data Repository, last updated in March 2024.

Use Cases

• Modeling riverbed morphology and erosion based on bathymetric lidar and sonar data.
• Creating high-resolution digital elevation models based on 1m topographic lidar raster and point cloud data.
• Analyzing surface water features and riparian zones based on orthophoto imagery.
• Investigating subsurface structures in a specific river pool based on ground-penetrating radar point data.

Strengths

• Includes multiple complementary data types: lidar, orthophotos, sonar, and GPR.
• Provides a detailed 1m composite raster dataset for a two-kilometer study area.
• Data is available in both raster (BIL, geoTiff) and point cloud (LAS) formats for flexibility.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total file size are unknown, which may limit suitability assessment.
