John Andrews from the Texas Data Repository Harvested Dataverse collected this dataset, last updated on 2024-03-18. It includes topographic and bathymetric lidar data, orthophotos, sonar, and ground-penetrating radar (GPR) data for the Devils River from Juno to Lake Amistad in Texas. The data covers a general area and includes a more detailed two-kilometer study section from Finnegan Springs to Dolan Falls.
Use Cases
- Modeling riverbed topography and bathymetry based on the combined lidar and sonar data.
- Creating high-resolution base maps for environmental studies using the orthophotos.
- Analyzing subsurface structures in a river pool based on the ground-penetrating radar (GPR) data.
- Conducting change detection or habitat mapping using the composite raster dataset of lidar and GPR.
Strengths
- Includes multiple complementary data types: lidar, orthophotos, sonar, and GPR.
- Provides a detailed composite dataset for a specific two-kilometer study area.
- Data is available in both raster (BIL, geoTiff) 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.
- Description metadata is limited; actual data quality requires manual inspection after download.
