Engineering Specialist I

State of North Carolina•Century Center Wake, NC

4d•$50,088 - $87,654

About The Position

The Photogrammetry Unit acquires aerial imagery and generates geospatial information products used for transportation planning, design, and construction. The unit also partners with other government agencies for statewide orthophotography and aerial LiDAR elevation data programs serving as NCDOT's subject matter experts for aerial surveying. We have two openings for an Engineering Specialist I to provide intermediate level technical support to lower-level technicians and engineers.

Requirements

Associate’s degree in an applicable area of engineering technology from an appropriately accredited institution and six (6) years of progressive technician experience; or High School or General Educational Development (GED) diploma and eight (8) years of progressive technician experience; or an equivalent combination of education and experience.
Knowledge and understanding of the concepts, practices, and theories of professional transportation and geomatics engineering used in photogrammetry, LiDAR surveying, and conventional surveying related to highway location, design, and construction.
Knowledge and skill in inspecting, analyzing, and evaluating aerial image acquisition parameters, image measurements for planimetric mapping, digital terrain models, Aerotriangulation data, Aerotriangulation Reports, and Airborne Survey Reports.
Experience expressing moderately complex technical work in photogrammetric processes in adherence with unit codes/standards.
Demonstrated ability effectively using verbal and nonverbal skills to express intermediate level technical facts in a clear, concise, and organized manner; and maintaining moderately complex records and work specific notes.
Demonstrated ability perceiving overlapping aerial imagery stereoscopically in three dimensions and interpreting planimetric and terrain features relatively correct.

Responsibilities

Inspect, analyze, evaluate, and recommend corrective action for both consultant and internally generated Aerotriangulation Reports, Airborne Survey Reports, Image Alignment Reports, and flight plan and acquired aerial image forward overlap, side overlap, and ground sample distance pixel size.
Analyze both consultant and internally generated manual and automated image measurements for aerotriangulation and non-metric camera image alignment, planimetric mapping, and various elevation products.
Analyze cross sections, edit and record discrepancies for resolution with Resident Engineers’ Office, and computes earthwork volume pay quantities.
Operate sophisticated photogrammetric analytical stereoplotting instrument and software to stereoscopically measure image coordinates for metric camera imagery aerotriangulation.
Operate various non-metric camera imagery software programs to align imagery to ground coordinates, produce orthoimagery, 3-D point clouds, and classify 3-D point cloud data for ground elevations.
