John Andrews collected topographic and bathymetric lidar, orthophotos, sonar, and ground-penetrating radar data in and along the Devils River from Juno to Lake Amistad, Texas. The data includes 1-meter raster and point cloud formats, with a detailed study area covering a two-kilometer pool from Finnegan Springs to Dolan Falls. The dataset was last updated on March 18, -2024.
Use Cases
- Modeling riverbed topography and bathymetry based on the lidar point cloud data.
- Creating high-resolution base maps for environmental studies using the orthophotos.
- Analyzing subsurface structures in a specific river pool based on the sonar and GPR composite data.
Strengths
- Includes multiple complementary data types: lidar, orthophotos, sonar, and GPR.
- Provides a detailed 1-meter resolution composite dataset for a two-kilometer study area.
- Data extents are defined by an index map, clarifying spatial coverage.
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.
