John Andrews collected topographic and bathymetric lidar, orthophotos, sonar, and GPR data for the Devils River in Texas. The dataset includes 1m raster and point cloud formats for the main river section and detailed sonar and GPR data for a two-kilometer pool from Finnegan Springs to Dolan Falls. The data was last updated on March 18, 2024.
Use Cases
- Generate high-resolution digital elevation models based on the 1m topographic and bathymetric lidar data.
- Conduct detailed underwater feature analysis based on the sonar and GPR point data for the Finnegan Springs to Dolan Falls pool.
- Create composite terrain visualizations based on the 1m composite raster dataset combining lidar and GPR data.
- Perform orthorectification and land cover mapping based on the provided orthophotos in geoTiff format.
Strengths
- Includes multiple complementary data types: lidar, orthophotos, sonar, and GPR.
- Provides a detailed, high-resolution study area with composite data for a two-kilometer river pool.
- Data is available in both raster (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.
