Iroquois National Wildlife Refuge GPS Control Survey and LiDAR Mapping

The U.S. Fish and Wildlife Service (USFWS) requested updated topographic mapping of 11,000 acres for future land planning and management. The widely varied terrain and density of vegetation across this large project area required the use of aerial LiDAR because it is the best solution to achieve the appropriate level of detail and accuracy. The project also needed ideal weather and site conditions for aerial data gathering so timing of the flight was critical.

The RETTEW team collected aerial LiDAR data and produced the digital mapping files. Through this teaming opportunity, we were able to collaborate on our efforts with an ongoing LiDAR mapping project in Genesee County for the U.S. Natural Resources Conservation Service. RETTEW’s extensive survey resources and progressive thinking allowed us to complete this project efficiently and economically and provided supremely accurate data for USFWS’s future planning decisions.
