Our team performed all imagery acquisition and processing as well as most of the LiDAR acquisition (approximately 3,100 square miles) for this project. In order to enable capture of peak flood conditions, typical orthoimagery acquisition specifications for no clouds or haze, etc. were not required for this project.
One of the most efficient ways to assess damage across large expanses is to acquire aerial imagery from manned, fixed-wing aircraft. About a week and a half after Hurricane Fiona hit, the U.S. Department of Agriculture (USDA) sent a task order for imagery over the entire island to our team, and we proceeded to design and execute the imagery acquisition efforts.
In 2022, the US Geological Survey (USGS) required lidar data and derivative products over a 1,500-square-mile area in central Minnesota. Through its Geospatial Products and Services Contract (GPSC4) our team was awarded a task order to provide QL1 lidar and hydro-flattening breaklines over this area, and the challenge was clear.
On May 22, 2019, an EF-3 tornado hit Jefferson City, MO. Within a few hours, several geospatial entities within the state established a data acquisition plan. Because of the emergency nature of this project, it was essential to provide data as quickly as possible to assist first responders in relief and recovery activities.
Thomas Jefferson’s Monticello plantation in Charlottesville, VA was the subject of an archeological excavation that employed airborne lidar to provide archeologists with insights into the property. Aircraft equipped with precision lidar sensors obtained high-density lidar data of 33 square miles of the plantation, which revealed areas of high interest.
Our team was retained by the South Carolina Department of Transportation, District 5 to perform emergency 3D laser scanning surveys on a ¾ mile segment of Interstate 95 running northerly from the I-95/I-20 Interchange.
Bowman provided 3-D laser scanning, planning and zoning expertise, landscape architecture, survey, site civil engineering, structural engineering and comprehensive construction administration/observation services.
Documented every cubic inch of the home of the Houston Symphony. The building is a massive structure spanning an entire city block. Our team laser scanned and modeled from the center stage to the marble-clad exterior, down to the mechanical room. The scope also included scanning harness-only areas directly above the stage.
Our laser scanning team was deployed to the project site to begin the meticulous work of measuring the gutted building, inside and out, with accuracy within”. The crew was working while the building was in the middle of demolition, and the project involved four phases of scanning to work around the other contractors.
Our 3D laser scanning team used the latest in laser scanning technology to document every facet of the ornate interior, and used the data to compile a unified point cloud. The point cloud captures the surfaces of the room in three dimensional space.
