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

The Devils River in Texas, from Juno to Lake Amistad, is the focus of this geospatial dataset. It includes topographic and bathymetric lidar data in raster and point formats, orthophotos, and detailed sonar and ground-penetrating radar (GPR) data for a two-kilometer pool near Dolan Falls. The dataset was authored by John Andrews and last updated on March 18, —2024.

Use Cases

• Generate high-resolution digital elevation models based on the 1-meter topographic and bathymetric lidar raster data.
• Analyze underwater riverbed morphology based on the bathymetric lidar and sonar point data.
• Create orthorectified base maps for environmental monitoring using the provided geoTiff orthophotos.
• Fuse subsurface and surface data for geological study based on the composite lidar+GPR raster dataset.
• Delineate study area boundaries for analysis using the provided index map (SHP) depicting data extents.

Strengths

• Includes multiple complementary data types: lidar, orthophotos, sonar, and ground-penetrating radar (GPR).
• Provides data for a detailed study area—a two-kilometer pool—with specialized composite datasets.
• Data is available in both raster (BIL) and point cloud (LAS) formats for different analytical needs.

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.
• Description metadata is limited; actual data quality requires manual inspection after download.
