The Tualatin River National Wildlife Refuge is an urban paradise. There
are only a few set asides in North America that are both in highly devel-oped
areas and devoted to maintaining and managing resources and
species. Since its establishment in 1992, the staff has worked diligently
to rehab the land back to a natural state. To aide this continuing effort,
Continental Mapping was commissioned to provide high accuracy
mapping. The project was in support of ongoing inventory and monitor-ing
activities, refuge management, landscape design, hydrogeomor-phological
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-condi-tioned
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.
