Topobathy lidar data covering approximately 225 square miles along Tampa Bay shores. The data were collected by Dewberry using a CZMIL Nova system between January 26 and February 27, 2021. It includes 52 tiles of 5000 m x 5000 m DEMs with points classified as ground, water surface, bathymetric bottom, and submerged objects.
Use Cases
- Model coastal erosion and sediment transport based on classified ground and bathymetric bottom points.
- Analyze submerged object distribution for navigation safety based on the 'submerged object' classification.
- Create integrated land-sea elevation models for flood risk assessment based on topobathy data.
- Study water surface dynamics using the water surface and derived water surface point classifications.
Strengths
- Data covers approximately 225 square miles, providing a substantial coastal area.
- Includes 52 discrete 5000 m x 5000 m DEM tiles for manageable spatial analysis.
- Points are classified into specific categories like ground, water surface, and bathymetric bottom.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Data may reflect geographic bias inherent to the specific Tampa Bay collection area.
