NV5 Geospatial has been at the forefront of collecting and processing high-resolution lidar and orthoimagery for coastal and marine resource programs for over four decades, offering experience in acquiring data with close attention to tides, water clarity, airspace restrictions, and weather patterns to ensure success. We also offer integrated GIS solutions to harness data into actionable information. Guided by coastal geospatial experts, our data products, analytics, and enterprise GIS solutions inform resource management, habitat mapping, and coastal resiliency planning for future generations.
Using topobathymetric lidar, processing algorithms, feature extraction, and photogrammetric tools, we model shoreline topography, map the land water interface, and depict coastal features with high detail and accuracy for effective nautical charting, resource management, urban development, land management, infrastructure maintenance, and emergency response.
Benthic Habitat Mapping
From topobathymetric lidar data and innovative processing tools, we can classify benthic and submerged environments (seagrass, kelp beds, algae, coral reefs) to identify critical habitat for marine species and facilitate effective resource management. Our radiometric calibration of lidar intensities is a significant contributor to mapping the underwater environment and sea floor.
Hydrology, Hydraulics, and Inundation
High-resolution lidar data improves flood hazard maps; predictive flood, storm surge, and tsunami inundation maps; and hydrologic and hydraulic modeling within coastal catchments. Our data is advancing coastal intelligence and resiliency to better protect and prepare communities and shoreline resources in a dynamic coastal environment.
We have delivered marine eGIS solutions to serve as decision support tools for managing marine minerals, improving sea turtle safety, and mapping essential fish habitat, and we have updated environmental sensitivity index (ESI) maps for a number of states to ensure oil spill response preparedness.

Coastal Land Cover & Change Analysis
With the aid of recurring surveys and temporal comparisons, our trend analyses quantify, model, and visualize important changes taking place along coastal environments. Detecting and quantifying these patterns empowers planners and resource managers to accurately evaluate, respond, monitor, predict or mitigate change, improving knowledge and enhancing preparedness.
Updated National Hydrography Dataset (NHD)
Combining models of vegetation structure with hydrologic models aids in understanding how terrain and vegetation affects water movement throughout a watershed. We have developed a lidar-driven methodology to update the National Hydrography Dataset (NHD) and improve hydrologic flow modeling and stream network maps for coastal watersheds.
