Devils River in Texas, from Juno to Lake Amistad, is covered by this dataset. It includes topographic and bathymetric lidar data in raster and point formats, orthophotos, and sonar and GPR data for a detailed study area around Finnegan Springs. The data was contributed by John Andrews via the Texas Data Repository and was last updated in March 2024.
Use Cases
- Generate high-resolution digital elevation models based on the 1m topographic and bathymetric lidar raster data.
- Conduct detailed geophysical analysis of a river pool using the composite lidar and GPR raster dataset.
- Create orthorectified base maps for environmental monitoring using the provided geoTiff orthophotos.
- Analyze underwater riverbed morphology based on the sonar and GPR point data.
Strengths
- Includes multiple complementary data types: lidar, orthophotos, sonar, and GPR.
- Provides a focused, high-detail composite dataset for a specific two-kilometer pool section.
- 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.
