Multiple remote sensing data types collected along the Devils River in Texas include topographic and bathymetric lidar, orthophotos, sonar, and ground-penetrating radar. The dataset, authored by John Andrews and harvested by the Texas Data Repository, was last updated on March 18, 2024. A detailed composite raster of lidar and GPR data is provided for a two-kilometer study area from Finnegan Springs to Dolan Falls.
Use Cases
- Modeling riverbed topography and bathymetry based on the 1m lidar raster and point cloud data.
- Creating high-resolution base maps for GIS analysis based on the provided orthophotos.
- Analyzing subsurface riverbed composition based on the ground-penetrating radar point data.
- Conducting detailed habitat or geomorphological studies in the Finnegan Springs to Dolan Falls pool based on the composite lidar+GPR raster.
Strengths
- Includes multiple complementary data types (lidar, orthophotos, sonar, GPR) for a single geographic area.
- Provides a 1m resolution composite raster dataset for a focused two-kilometer study area.
- Data extents are defined by an index map in shapefile format.
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.
