Sun Prairie, Wis.-based Continental Mapping Consultants delivered a LiDAR and orthophoto mapping project to the U.S. Fish and Wildlife Service for the Tualatin National Wildlife Refuge in Portland, Ore.

The project was in support of ongoing inventory and monitoring activities, refuge management, landscape design, hydrogeomorphological assessments and planned vegetation mapping efforts.

The Fish and Wildlife Service contracted with Continental Mapping to acquire LiDAR and imagery of a 10-square-mile area around the Wapato Lake Unit and deliver a bare earth surface, a hydro-conditioned DEM, a vegetation canopy DEM and orthophotos.

As part of the processing, Continental Mapping completed hydro-enforcement, hydro-conditioning and hydro-flattening, and developed a vegetation canopy height model by extracting first return data from the point cloud.

“We greatly enjoyed working with Continental Mapping because they demonstrated a commitment to quality and schedule, and made adjustments when necessary,” said Dave Taylor Sr., land surveyor with the Fish and Wildlife Service. “I believe the use of a helicopter in the acquisition of the high resolution LiDAR dataset required by our project was an important component of the overall success. The deliverables exceeded our expectations, and our plan is to use this data for modeling of designs that will enable more efficient flows of water to critical habitat areas.”

“This project is another example of our ability to provide coast-to-coast lidar and imagery solutions for federal agencies. We look forward to future partnerships with the U.S. Fish and Wildlife Service,” said Dave Hart, president of Continental Mapping.
