Devils River Topographic and Bathymetric Lidar, Orthophotos, and Sonar Data

Data collected in and along the Devils River from Juno to Lake Amistad, Texas includes topographic and bathymetric lidar in 1m raster and point formats, orthophotos, and an index map. For a detailed two-kilometer study area from Finnegan Springs to Dolan Falls, sonar and ground-penetrating radar point data and a composite raster are also provided. The dataset was authored by John Andrews and last updated on March 18, 2024.

Use Cases

• Model riverbed and channel morphology based on bathymetric lidar and sonar data.
• Create high-resolution base maps for environmental studies using the orthophotos.
• Analyze subsurface structures in a river pool using the ground-penetrating radar point data.
• Delineate data coverage and extents for project planning using the provided index map.

Strengths

• Includes multiple complementary data types: lidar, orthophotos, sonar, and ground-penetrating radar.
• Provides a focused, detailed dataset for a two-kilometer river pool study area.
• Data is available in both raster (1m BIL) and point (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.
