John Andrews from the Texas Data Repository Harvested Dataverse collected topographic and bathymetric lidar, orthophotos, sonar, and GPR data in and along the Devils River from Juno to Lake Amistad, Texas. The data includes 1m raster and point cloud formats, with a detailed study area of a two-kilometer pool from Finnegan Springs to Dolan Falls. The dataset was last updated on March 18, -2024.
Use Cases
- Model riverbed and channel morphology based on bathymetric lidar and sonar data.
- Create high-resolution terrain maps based on topographic lidar and orthophoto data.
- Analyze subsurface geological structures based on Ground Penetrating Radar (GPR) data.
- Conduct detailed habitat or hydrological studies in the Finnegan Springs to Dolan Falls pool area.
Strengths
- Includes multiple complementary data types: lidar, orthophotos, sonar, and GPR.
- Provides a detailed composite raster dataset for a specific two-kilometer study area.
- Data is available in both raster (1m BIL) and point cloud (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.
