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

Data collected in and along the Devils River from Juno to Lake Amistad, Texas includes topographic and bathymetric lidar, orthophotos, sonar, and ground-penetrating radar (GPR) data. The dataset, authored by John Andrews and hosted by the Texas Data Repository, was last updated on March 18, 2024. It includes a detailed study area of a two-kilometer pool from Finnegan Springs to Dolan Falls.

Use Cases

• Modeling river channel morphology and bathymetry based on the topographic and bathymetric lidar data.
• Creating high-resolution base maps for environmental studies using the orthophoto imagery.
• Analyzing subsurface riverbed composition and structure based on the sonar and GPR point data.
• Conducting detailed habitat or geomorphological studies in the Finnegan Springs to Dolan Falls pool using the composite lidar+GPR raster.

Strengths

• Includes multiple complementary data types (lidar, orthophotos, sonar, GPR) for a holistic view.
• Provides a focused, high-detail composite dataset for a specific two-kilometer study area.
• Data is provided in both raster (BIL, GeoTIFF) and point (LAS) formats for flexibility.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The total spatial extent and data volume are not specified in the provided metadata.
