Dam Digital Twin

A photogrammetry-based digital twin workflow that produced georeferenced 3D mesh, point cloud, orthomosaic, and elevation products for dam infrastructure management.

Context

WSSC needed high-resolution spatial products to support development of a digital twin for the T. Howard Duckett Dam. The work connected drone imagery, photogrammetry, and infrastructure data preparation to support future asset management, monitoring, and engineering analysis.

Challenge

A digital twin requires more than a visually impressive 3D model. The spatial outputs need to be georeferenced, accurate, clean, and usable across downstream workflows such as BIM model creation, structural monitoring, asset management, and future analytics.

My Role

I led the generation, processing, and refinement of the photogrammetric products. My role focused on producing georeferenced 3D mesh models, point clouds, orthomosaics, and elevation products suitable for infrastructure workflows.

Approach

I processed drone imagery into 3D and 2D geospatial deliverables, refined model quality, and prepared outputs for integration into digital twin and BIM-oriented workflows. The work emphasized both visual detail and technical usability.

Output

The project produced georeferenced 3D mesh models, photogrammetric point clouds, high-resolution orthomosaics, and elevation products.

Impact

The outputs provided a spatial foundation for WSSC's dam digital twin. They supported infrastructure documentation, monitoring, asset management, and future analytics for critical water infrastructure.
