Lake Seminole Topographic Lidar Elevation Data from 2024

Topographic lidar elevation data for Lake Seminole, covering parts of Alabama, Florida, and Georgia. The data was collected in 2024 using a Teledyne ALTM Galaxy PRIME sensor by the USACE Joint Airborne Lidar Bathymetry Technical Center of Expertise (JALBTCX). Processed data is provided in LAS files, tiled into 1-km by 1-km boxes, with horizontal positions referenced to NAD83 (2011) and vertical positions referenced to the NAD83 (2011) ellipsoid in meters.

Use Cases

• Modeling coastal terrain and elevation based on high-resolution lidar point clouds.
• Analyzing landform changes and geomorphic processes around Lake Seminole.
• Creating digital elevation models (DEMs) for hydrological or flood risk studies.
• Integrating topographic data into regional GIS systems for environmental planning.

Strengths

• Data is tiled into standardized 1-km by 1-km boxes for systematic analysis.
• Horizontal and vertical positions use a defined geodetic reference (NAD83 (2011)).
• Data was collected using a specific, named sensor (Teledyne ALTM Galaxy PRIME).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total data size are unknown, which may limit suitability assessment.
