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

The Devils River in Texas, from Juno to Lake Amistad, is the geographic scope of this dataset. It includes topographic and bathymetric lidar data in raster and point formats, orthophotos, sonar, and ground-penetrating radar data for a detailed study area near Finnegan Springs. The data was contributed by John Andrews via the Texas Data Repository and was last updated in March 2024.

Use Cases

• Modeling riverbed topography and bathymetry based on the lidar point cloud and raster data.
• Creating high-resolution base maps for environmental studies using the provided orthophotos.
• Analyzing subsurface features in a specific river pool using the composite lidar and ground-penetrating radar dataset.
• Mapping the spatial extent of available data layers using the provided index map shapefile.

Strengths

• Includes multiple complementary data types: lidar, orthophotos, sonar, and ground-penetrating radar.
• Provides data for a broad survey area (Juno to Lake Amistad) and a more detailed two-kilometer study pool.
• Data is available in both point cloud (LAS) and raster (BIL) 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.
• Freshness should be verified; the last update timestamp is 2024-03-18 10:56:03.
