Fugro Maps Elevation in Texas River Basins

Fugro has launched a regional elevation survey to aid flood risk assessment and infrastructure planning in south‑central Texas. Backed by the Texas Water Development Board, the assignment spans four river basins, covering roughly 41,381 square kilometres across 34 fast‑growing communities.Guadalupe River BasinSan Antonio River BasinLower Colorado River BasinLavaca River Basin

Remote Sensing Methods and Delivery

After enduring multiple floods in recent years, these communities are revising hazard‑mitigation strategies as part of broader infrastructure planning, with upgrades to drainage networks, transportation corridors, and water service.

Delivery is coordinated by the Texas Geographic Information Office (TxGIO), which maintains consistent, high‑quality geographic information used statewide for planning and public safety. Through its long‑standing StratMap partnership, Fugro is conducting high‑accuracy airborne lidar acquisition to give state and local partners a clear, current view of the terrain. The lidar work typically combines flight planning, calibration, and repeatable collection runs with cloud-based processing steps such as point classification, surface modeling, and quality checks, and it can be integrated with other authoritative geospatial layers to ensure the final elevation products align with local planning needs.

To standardize collection across the project area, the team employs precise satellite positioning to limit new ground control, while Fugro’s cloud processing accelerates turnaround and enhances data quality; derived point clouds are delivered to the state more quickly. Depending on project requirements, Fugro can also complement lidar with photogrammetry, mobile mapping, and uncrewed aerial vehicle surveys, and it can integrate hydrographic surveys to capture river and channel bathymetry so flood models reflect both land elevation and in-channel conditions.

Why the Dataset Matters

Beyond this regional program, Fugro’s elevation mapping services commonly support topographic mapping, flood risk mapping, corridor and site planning, and engineering-ready terrain deliverables. These services help improve confidence in design and mitigation decisions through survey-grade, high-accuracy elevation surfaces, faster data delivery cycles, and clearer risk visibility for planners and emergency managers. Typical applications include flood modeling, urban growth planning, transportation and utility design, environmental monitoring, and change detection, with geospatial data processed and analyzed into usable outputs such as terrain surfaces, contours, and digital twin-ready 3D context for asset and resilience planning. In coastal and offshore settings, the same elevation and bathymetry capabilities can support ocean climate action work by informing shoreline resilience, habitat restoration planning, and sea-level-rise adaptation.Current elevation information is essential for communities evaluating flood exposure and reinforcing infrastructure, said Ellen St. Romain, Lidar Program Specialist at TxGIO. The initiative equips planners, engineers, and emergency managers with reliable evidence to guide choices that safeguard residents and assets.High-accuracy elevation models help translate storm and river behavior into actionable maps, enabling communities to target upgrades where they will reduce risk most.
